In this article, we will go through the steps to quickly build the Microsoft Entra ID OIDC enterprise SSO sign-in experience (user authentication) with Expo (React Native) and Logto.

Prerequisites

• A running Logto instance. Check out the introduction page to get started.
• Basic knowledge of Expo (React Native).
• A usable Microsoft Entra ID OIDC enterprise SSO account.

Create an application in Logto​

Logto is based on OpenID Connect (OIDC) authentication and OAuth 2.0 authorization. It supports federated identity management across multiple applications, commonly called Single Sign-On (SSO).

To create your Native app application, simply follow these steps:

1. Open the Logto Console. In the "Get started" section, click the "View all" link to open the application frameworks list. Alternatively, you can navigate to Logto Console > Applications, and click the "Create application" button.
2. In the opening modal, click the "Native app" section or filter all the available "Native app" frameworks using the quick filter checkboxes on the left. Click the "Expo" framework card to start creating your application.
3. Enter the application name, e.g., "Bookstore," and click "Create application".

🎉 Ta-da! You just created your first application in Logto. You'll see a congrats page which includes a detailed integration guide. Follow the guide to see what the experience will be in your application.

Integrate Expo with Logto​

Installation​

Install Logto SDK and peer dependencies via your favorite package manager:

npm i @logto/rn
npm i expo-crypto expo-secure-store expo-web-browser @react-native-async-storage/async-storage

yarn add @logto/rn
yarn add expo-crypto expo-secure-store expo-web-browser @react-native-async-storage/async-storage

pnpm add @logto/rn
pnpm add expo-crypto expo-secure-store expo-web-browser @react-native-async-storage/async-storage

The @logto/rn package is the SDK for Logto. The remaining packages are its peer dependencies. They couldn't be listed as direct dependencies because the Expo CLI requires that all dependencies for native modules be installed directly within the root project's package.json.

Init Logto provider​

Import and use LogtoProvider to provide a Logto context:

import { LogtoProvider, LogtoConfig } from '@logto/rn';

const config: LogtoConfig = {
  endpoint: '<your-logto-endpoint>',
  appId: '<your-application-id>',
};

const App = () => (
  <LogtoProvider config={config}>
    <YourAppContent />
  </LogtoProvider>
);

Implement sign-in and sign-out​

Before we dive into the details, here's a quick overview of the end-user experience. The sign-in process can be simplified as follows:

1. Your app invokes the sign-in method.
2. The user is redirected to the Logto sign-in page. For native apps, the system browser is opened.
3. The user signs in and is redirected back to your app (configured as the redirect URI).

Switch to the application details page of Logto Console. Add a native redirect URI (for example, io.logto://callback), then click "Save".

• For iOS, the redirect URI scheme does not really matter since the ASWebAuthenticationSession class will listen to the redirect URI regardless of if it's registered.

• For Android, the redirect URI scheme must be filled in Expo's app.json file, for example:

  app.json

  {
    "expo": {
      "scheme": "io.logto"
    }
  }
  

Now back to your app, you can use useLogto hook to sign in and sign out:

import { useLogto } from '@logto/rn';
import { Button } from 'react-native';

const Content = () => {
  const { signIn, signOut, isAuthenticated } = useLogto();

  return (
    <div>
      {isAuthenticated ? (
        <Button title="Sign out" onPress={async () => signOut()} />
      ) : (
        // Replace the redirect URI with your own
        <Button title="Sign in" onPress={async () => signIn('io.logto://callback')} />
      )}
    </div>
  );
};

Checkpoint: Test your application​

Now, you can test your application:

1. Run your application, you will see the sign-in button.
2. Click the sign-in button, the SDK will init the sign-in process and redirect you to the Logto sign-in page.
3. After you signed in, you will be redirected back to your application and see the sign-out button.
4. Click the sign-out button to clear token storage and sign out.

Add Microsoft Entra ID OIDC enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with Expo as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up Azure AD SSO application​

Step 1: Create an Microsoft EntraID OIDC application​

1. Go to the Microsoft Entra admin center and sign in as an administrator.

2. Browse to Identity > Applications > App registrations.

3. Select New registration.

4. Enter the application name and select the appropriate account type for your application.

5. Select Web as the application platform.

6. Copy and paste the redirect URI from Logto's SSO settings page. The redirect URI is the URL where the user is redirected after they have authenticated with Microsoft Entra ID.

6. Click Register to create the application.

Step 2: Configure Microsoft Entra ID OIDC SSO at Logto​

After successfully creating an Microsoft Entra OIDC application, you will need to provide the IdP configurations back to Logto. Navigate to the Connection tab at Logto Console, and fill in the following configurations:

1. Client ID: A unique identifier assigned to your OIDC application by the Microsoft Entra. This identifier is used by Logto to identify and authenticate the application during the OIDC flow. You can find it in the application overview page as Application (client) ID.

2. Client Secret: Create a new client secret and copy the value to Logto. This secret is used to authenticate the OIDC application and secure the communication between Logto and the IdP.

3. Issuer: The issuer URL, a unique identifier for the IdP, specifying the location where the OIDC identity provider can be found. It is a crucial part of the OIDC configuration as it helps Logto discover the necessary endpoints.

   Instead of manually provide all these OIDC endpoints, Logto fetch all the required configurations and IdP endpoints automatically. This is done by utilizing the issuer url you provided and making a call to the IdP's discover endpoint.

   To get the issuer URL, you can find it in the Endpoints section of the application overview page.

   Locate the OpenID Connect metadata document endpoint and copy the URL WITHOUT the trailing path .well-known/openid-configuration. This is because Logto will automatically append the .well-known/openid-configuration to the issuer URL when fetching the OIDC configurations.

4. Scope (Optional): Logto automatically includes the required scopes (openid, profile, and email) in all requests. You can specify additional scopes as a space-separated list if your application requires extra permissions or access levels from the IdP.

Click Save to finish the configuration process

Step 3: Additional scopes (Optional)​

Scopes define the permissions your app requests from users and control which data your app can access from their Microsoft Entra ID accounts. Requesting Microsoft Graph permissions requires configuration on both sides:

In Microsoft Entra admin center:

1. Navigate to Microsoft Entra ID > App registrations and select your application.
2. Go to API permissions > Add a permission > Microsoft Graph > Delegated permissions.
3. Select only the permissions your app requires:
   • OpenID permissions:
     • openid (Required) - Sign users in
     • profile (Required) - View users' basic profile
     • email (Required) - View users' email address
     • offline_access (Optional) - Required only if you enable Store tokens for persistent API access in the Logto connector and need to obtain refresh tokens for long-lived access to Microsoft Graph APIs.
   • API access (Optional): Add any additional permissions needed for your app. Common Microsoft Graph permissions include Mail.Read, Calendars.Read, Files.Read, etc. Browse the Microsoft Graph permissions reference to find available permissions.
4. Click Add permissions to confirm the selection.
5. If your app requires admin consent for certain permissions, click Grant admin consent for [Your Organization].

In Logto Microsoft Entra ID connector:

1. Logto automatically includes openid, profile, and email scopes to retrieve basic user identity information. You can leave the Scopes field blank if you only need basic user information.
2. Add offline_access to the Scopes field if you plan to store tokens for persistent API access. This scope enables refresh tokens for long-lived API access.
3. Add additional scopes (separated by spaces) in the Scopes field to request more data from Microsoft Graph. Use standard scope names, for example: User.Read Mail.Read Calendars.Read

Step 4: Store tokens to access Microsoft APIs (Optional)​

If you want to access Microsoft Graph APIs and perform actions with user authorization, Logto needs to get specific API scopes and store tokens.

1. Add the required scopes in your Microsoft Entra admin center API permissions configuration and Logto Microsoft Entra ID connector.
2. Enable Store tokens for persistent API access in Logto Microsoft Entra ID connector. Logto will securely store Microsoft access and refresh tokens in the Secret Vault.
3. To ensure refresh tokens are returned, add the offline_access scope to your Microsoft Entra ID application permissions and include it in your Logto Microsoft Entra ID connector scopes. This scope allows your application to maintain access to resources for extended periods.

Step 5: Set email domains and enable the SSO connector​

Provide the email domains of your organization on the connector experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be exclusively limited to use your SSO connector as their only authentication method.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the Microsoft Entra ID OIDC enterprise SSO connector should be available now.

Enable Microsoft Entra ID OIDC enterprise SSO connector in Sign-in Experience​

You don’t need to configure enterprise connectors individually, Logto simplifies SSO integration into your applications with just one click.

1. Navigate to: Console > Sign-in & account > Sign-up and sign-in.
2. Enable the "Enterprise SSO" toggle.
3. Save changes.

Once enabled, a "Single Sign-On" button will appear on your sign-in page. Enterprise users with SSO-enabled email domains can access your services using their enterprise identity providers (IdPs).

To learn more about the SSO user experience, including SP-initiated SSO and IdP-initiated SSO, refer to User flows: Enterprise SSO.

Testing and Validation​

Return to your Expo (React Native) app. You should now be able to sign in with Microsoft Entra ID OIDC enterprise SSO. Enjoy!

Integrate iOS (Swift) with Logto​

Add Logto SDK as a dependency​

Use the following URL to add Logto SDK as a dependency in Swift Package Manager.

https://github.com/logto-io/swift.git

Since Xcode 11, you can directly import a Swift package w/o any additional tool.

We do not support Carthage and CocoaPods at the time due to some technical issues.

Init LogtoClient​

Initialize the client by creating a LogtoClient instance with a LogtoConfig object.

import Logto
import LogtoClient

let config = try? LogtoConfig(
  endpoint: "<your-logto-endpoint>", // E.g. http://localhost:3001
  appId: "<your-app-id>"
)
let client = LogtoClient(useConfig: config)

let config = try? LogtoConfig(
  // ...
  usingPersistStorage: false
)

Sign in​

Before we dive into the details, here's a quick overview of the end-user experience. The sign-in process can be simplified as follows:

1. Your app invokes the sign-in method.
2. The user is redirected to the Logto sign-in page. For native apps, the system browser is opened.
3. The user signs in and is redirected back to your app (configured as the redirect URI).

Configure redirect URI​

Let's switch to the Application details page of Logto Console. Add a Redirect URI io.logto://callback and click "Save changes".

Sign-in and sign-out​

You can use client.signInWithBrowser(redirectUri:) to sign in the user and client.signOut() to sign out the user.

For example, in a SwiftUI app:

struct ContentView: View {
  @State var isAuthenticated: Bool

  init() {
    isAuthenticated = client.isAuthenticated
  }

  var body: some View {
    VStack {
      if isAuthenticated {
        Button("Sign Out") {
          Task { [self] in
            await client.signOut()
            isAuthenticated = false
          }
        }
      } else {
        Button("Sign In") {
          Task { [self] in
            do {
              try await client.signInWithBrowser(redirectUri: "${
                props.redirectUris[0] ?? 'io.logto://callback'
              }")
              isAuthenticated = true
            } catch let error as LogtoClientErrors.SignIn {
              // error occured during sign in
            } catch {
              // other errors
            }
          }
        }
      }
    }
  }
}

Checkpoint: Test your application​

Now, you can test your application:

1. Run your application, you will see the sign-in button.
2. Click the sign-in button, the SDK will init the sign-in process and redirect you to the Logto sign-in page.
3. After you signed in, you will be redirected back to your application and see the sign-out button.
4. Click the sign-out button to clear token storage and sign out.

Add Google Workspace enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with iOS (Swift) as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up Google Cloud Platform​

Step 1: Create a new project on Google Cloud Platform​

Before you can use Google Workspace as an authentication provider, you must set up a project in the Google API Console to obtain OAuth 2.0 credentials, If you already have a project, you can skip this step. Otherwise, create a new project under your Google organization.

Step 2: Config the consent screen for your application​

In order to create a new OIDC credential, you need to configure the consent screen for your application.

1. Navigate to the OAuth consent screen page and select the Internal user type. This will make the OAuth application only available to users within your organization.

2. Fill in the Consent Screen settings following the instructions on the page. You need to provide the following minimum information:

• Application name: The name of your application. It will be displayed on the consent screen.
• Support email: The support email of your application. It will be displayed on the consent screen.

3. Set the Scopes for your application. In order to retrieve the user's identity information and email address properly from the IdP, Logto SSO connectors need to grant the following scopes from the IdP:

• openid: This scope is required for OIDC authentication. It is used to retrieve the ID token and get access to the userInfo endpoint of the IdP.
• profile: This scope is required for accessing the user's basic profile information.
• email: This scope is required for accessing the user's email address.

Click the Save button to save the consent screen settings.

Step 3: Create a new OAuth credential​

Navigate to the Credentials page and click the Create Credentials button. Select the OAuth client ID option from the dropdown menu to create a new OAuth credential for your application.

Continue setting up the OAuth credential by filling up the following information:

1. Select the Web application as the application type.
2. Fill in the Name of your client application, Logto SSO Connector for example. This will help you to identify the credentials in the future.
3. Fill in the Authorized redirect URIs with the Logto callback URI. This is the URI that Google will redirect the user's browser after successful authentication. After a user successfully authenticates with the IdP, the IdP redirects the user's browser back to this designated URI along with an authorization code. Logto will complete the authentication process based on the authorization code received from this URI.
4. Fill in the Authorized JavaScript origins with the Logto callback URI's origin. This ensures only your Logto application can send requests to the Google OAuth server.
5. Click the Create button to create the OAuth credential.

Step 4: Set up Logto connector with the client credentials​

After successfully creating the OAuth credential, you will receive a prompt modal with the client ID and client secret.

Copy the Client ID and Client secret and fill in the corresponding fields on Logto’s SSO connector Connection tab.

Now you have successfully configured a Google Workspace SSO connector on Logto.

Step 5: Additional Scopes (Optional)​

Scopes define the permissions your app requests from users and control which data your app can access from their Google Workspace accounts. Requesting Google permissions requires configuration on both sides:

In Google Cloud Console:

1. Navigate to APIs & Services > OAuth consent screen > Scopes.
2. Click Add or Remove Scopes and select only the scopes your app requires:
   • Authentication (Required):
     • https://www.googleapis.com/auth/userinfo.email
     • https://www.googleapis.com/auth/userinfo.profile
     • openid
   • API access (Optional): Add any additional scopes needed for your app (e.g., Drive, Calendar, YouTube). Browse the Google API Library to find available services. If your app needs access to Google APIs beyond basic permissions, first enable the specific APIs your app will use (e.g., Google Drive API, Gmail API, Calendar API) in the Google API Library.
3. Click Update to confirm the selection.
4. Click Save and Continue to apply the changes.

In Logto Google Workspace connector:

1. Logto automatically includes openid, profile, and email scopes to retrieve basic user identity information. You can leave the Scopes field blank if you only need basic user information
2. Add additional scopes (separated by spaces) in the Scopes field to request more data from Google. Use full scope URLs, for example: https://www.googleapis.com/auth/calendar.readonly

Step 6: Store tokens to access Google APIs (Optional)​

If you want to access Google APIs and perform actions with user authorization, Logto needs to get specific API scopes and store tokens.

1. Add the required scopes in your Google Cloud Console OAuth consent screen configuration and Logto Google connector.
2. Enable Store tokens for persistent API access in Logto Google connector. Logto will securely store Google access and refresh tokens in the Secret Vault.
3. To ensure refresh tokens are returned, configure your Logto Google connector to enable Offline Access.

Step 7: Set email domains and enable the SSO connector​

Provide the email domains of your organization on Logto’s connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use your SSO connector as their only authentication method.

For more information about the Google Workspace SSO connector, please check Google OpenID Connector.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the Google Workspace enterprise SSO connector should be available now.

Step 1: Create an Azure AD SSO application​

Initiate the Azure AD SSO integration by creating an SSO application on the Azure AD side.

1. Go to the Azure portal and sign in as an administrator.
2. Select Microsoft Entra ID service.
3. Navigate to the Enterprise applications using the side menu. Click New application, and select Create your own application.

1. Enter the application name and select Integrate any other application you don't find in the gallery (Non-gallery).
2. Select Setup single sign-on > SAML.

1. Follow the instructions, as the first step, you will need to fill in the basic SAML configuration using the following information provided by Logto.

• Audience URI(SP Entity ID): It represents as a globally unique identifier for your Logto service, functioning as the EntityId for SP during authentication requests to the IdP. This identifier is pivotal for the secure exchange of SAML assertions and other authentication-related data between the IdP and Logto.
• ACS URL: The Assertion Consumer Service (ACS) URL is the location where the SAML assertion is sent with a POST request. This URL is used by the IdP to send the SAML assertion to Logto. It acts as a callback URL where Logto expects to receive and consume the SAML response containing the user's identity information.

Click Save to continue.

Step 2: Configure SAML SSO at Logto​

To make the SAML SSO integration work, you will need to provide the IdP metadata back to Logto. Let's switch back to the Logto side, and navigate to the Connection tab of your Azure AD SSO connector.

Logto provides three different ways to configure the IdP metadata. The easiest way is by providing the metadata URL of the Azure AD SSO application.

Copy the App Federation Metadata Url from your Azure AD SSO application's SAML Certificates section and paste it into the Metadata URL field in Logto.

Logto will fetch the metadata from the URL and configure the SAML SSO integration automatically.

Step 3: Configure user attributes mapping​

Logto provides a flexible way to map the user attributes returned from IdP to the user attributes in Logto. Logto will sync the following user attributes from IdP by default:

• id: The unique identifier of the user. Logto will read the nameID claim from the SAML response as the user SSO identity id.
• email: The email address of the user. Logto will read the email claim from the SAML response as the user primary email by default.
• name: The name of the user.

You may manage the user attributes mapping logic either on the Azure AD side or Logto side.

1. Map the AzureAD user attributes to Logto user attributes on Logto side.

   Visit the Attributes & Claims section of your Azure AD SSO application.

   Copy the following attribute names (with namespace prefix) and paste them into the corresponding fields in Logto.

   • http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress
   • http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name (Recommendation: update this attribute value map to user.displayname for better user experience)a

1. Map the AzureAD user attributes to Logto user attributes at the AzureAD side.

   Visit the Attributes & Claims section of your Azure AD SSO application.

   Click on Edit, and update the Additional claims fields based on the Logto user attributes settings:

   • update the claim name value based on the Logto user attributes settings.
   • remove the namespace prefix.
   • click Save to continue.

   Should end up with the following settings:

You may also specify additional user attributes on the Azure AD side. Logto will keep a record of the original user attributes returned from IdP under the user's sso_identity field.

Step 4: Assign users to the Azure AD SSO application​

Visit the Users and groups section of your Azure AD SSO application. Click on Add user/group to assign users to the Azure AD SSO application. Only users assigned to your Azure AD SSO application will be able to authenticate through the Azure AD SSO connector.

Step 5: Set email domains and enable the SSO connector​

Provide the email domains of your organization at Logto's connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use the SAML SSO connector as their only authentication method.

Please check Azure AD's official documentation for more details about the Azure AD SSO integration.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the Microsoft Entra ID SAML enterprise SSO connector should be available now.

In this article, we will go through the steps to quickly build the OIDC enterprise SSO sign-in experience (user authentication) with iOS (Swift) and Logto.

Prerequisites

• A running Logto instance. Check out the introduction page to get started.
• Basic knowledge of iOS (Swift).
• A usable OIDC enterprise SSO account.

Create an application in Logto​

Logto is based on OpenID Connect (OIDC) authentication and OAuth 2.0 authorization. It supports federated identity management across multiple applications, commonly called Single Sign-On (SSO).

To create your Native app application, simply follow these steps:

1. Open the Logto Console. In the "Get started" section, click the "View all" link to open the application frameworks list. Alternatively, you can navigate to Logto Console > Applications, and click the "Create application" button.
2. In the opening modal, click the "Native app" section or filter all the available "Native app" frameworks using the quick filter checkboxes on the left. Click the "iOS (Swift)" framework card to start creating your application.
3. Enter the application name, e.g., "Bookstore," and click "Create application".

🎉 Ta-da! You just created your first application in Logto. You'll see a congrats page which includes a detailed integration guide. Follow the guide to see what the experience will be in your application.

Integrate iOS (Swift) with Logto​

Add Logto SDK as a dependency​

Use the following URL to add Logto SDK as a dependency in Swift Package Manager.

https://github.com/logto-io/swift.git

Since Xcode 11, you can directly import a Swift package w/o any additional tool.

We do not support Carthage and CocoaPods at the time due to some technical issues.

Init LogtoClient​

Initialize the client by creating a LogtoClient instance with a LogtoConfig object.

import Logto
import LogtoClient

let config = try? LogtoConfig(
  endpoint: "<your-logto-endpoint>", // E.g. http://localhost:3001
  appId: "<your-app-id>"
)
let client = LogtoClient(useConfig: config)

let config = try? LogtoConfig(
  // ...
  usingPersistStorage: false
)

Sign in​

Before we dive into the details, here's a quick overview of the end-user experience. The sign-in process can be simplified as follows:

1. Your app invokes the sign-in method.
2. The user is redirected to the Logto sign-in page. For native apps, the system browser is opened.
3. The user signs in and is redirected back to your app (configured as the redirect URI).

Configure redirect URI​

Let's switch to the Application details page of Logto Console. Add a Redirect URI io.logto://callback and click "Save changes".

Sign-in and sign-out​

You can use client.signInWithBrowser(redirectUri:) to sign in the user and client.signOut() to sign out the user.

For example, in a SwiftUI app:

struct ContentView: View {
  @State var isAuthenticated: Bool

  init() {
    isAuthenticated = client.isAuthenticated
  }

  var body: some View {
    VStack {
      if isAuthenticated {
        Button("Sign Out") {
          Task { [self] in
            await client.signOut()
            isAuthenticated = false
          }
        }
      } else {
        Button("Sign In") {
          Task { [self] in
            do {
              try await client.signInWithBrowser(redirectUri: "${
                props.redirectUris[0] ?? 'io.logto://callback'
              }")
              isAuthenticated = true
            } catch let error as LogtoClientErrors.SignIn {
              // error occured during sign in
            } catch {
              // other errors
            }
          }
        }
      }
    }
  }
}

Checkpoint: Test your application​

Now, you can test your application:

1. Run your application, you will see the sign-in button.
2. Click the sign-in button, the SDK will init the sign-in process and redirect you to the Logto sign-in page.
3. After you signed in, you will be redirected back to your application and see the sign-out button.
4. Click the sign-out button to clear token storage and sign out.

Add OIDC enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with iOS (Swift) as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up OIDC application on your IdP​

Step 1: Create an OIDC application on your IdP​

Initiate the OIDC SSO integration by creating an application on the IdP side. You will need to provide the following configurations from the Logto server.

• Callback URI: The Logto Callback URI, also known as the Redirect URI or Reply URL, is a specific endpoint or URL that the IdP uses to redirect the user's browser after successful authentication. After a user successfully authenticates with the IdP, the IdP redirects the user's browser back to this designated URI along with an authorization code. Logto will complete the authentication process based on authorization code received from this URI.

Fill in the Logto Callback URI in your IdP OIDC application settings form and continue to create the application. (Most of the OIDC IdPs provide a wide range of application types to choose from. To create a web-based SSO connector on Logto, please choose the Web Application type.)

Step 2: Configure OIDC SSO on Logto​

After successfully creating an OIDC application on the IdP side, you will need to provide the IdP configurations back to Logto. Navigate to the Connection tab, and fill in the following configurations:

• Client ID: A unique identifier assigned to your OIDC application by the IdP. This identifier is used by Logto to identify and authenticate the application during the OIDC flow.
• Client Secret: A confidential secret shared between Logto and the IdP. This secret is used to authenticate the OIDC application and secure the communication between Logto and the IdP.
• Issuer: The issuer URL, a unique identifier for the IdP, specifying the location where the OIDC identity provider can be found. It is a crucial part of the OIDC configuration as it helps Logto discover the necessary endpoints. To make the configuration process easier. Logto will automatically fetch the required OIDC endpoints and configurations. This is done by utilizing the issuer you provided and making a call to the IdP's OIDC discover endpoints. It is imperative to ensure that the issuer endpoint is valid and accurately configured to enable Logto to retrieve the required information correctly. After a successful fetch request, you should be able to see the parsed IdP configurations under the issuers section.

Step 3: Configure scopes (Optional)​

Scopes define the permissions your app requests from users and control which data your app can access from their enterprise accounts.

Setting up scopes requires configuration on both sides:

1. Your Identity Provider (IdP): Configure which permissions are allowed for authorization in your IdP console
   • Some IdPs enable all public scopes by default (no action needed)
   • Others require you to explicitly grant permissions
2. Logto enterprise connector: Specify which scopes to request during authentication in the Logto OIDC enterprise connector settings > Scopes field.
   • Logto always includes the openid, profile, and email scopes to retrieve basic user identity information, regardless of your custom scope settings.
   • You can add additional scopes (separated by spaces) to request more information from the IdP.

Step 4: Store tokens to access third-party APIs (Optional)​

If you want to access the Identity Provider's APIs and perform actions with user authorization, Logto needs to get specific API scopes and store tokens.

1. Add the required scopes in the scope field following the instructions above
2. Enable Store tokens for persistent API access in the Logto OIDC enterprise connector. Logto will securely store access tokens in the Secret Vault.
3. For standard OIDC identity providers, the offline_access scope must be included to obtain a refresh token, preventing repeated user consent prompts.

Step 5: Set email domains and enable the SSO connector​

Provide the email domains of your organization on Logto’s connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use your SSO connector as their only authentication method.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the OIDC enterprise SSO connector should be available now.

Enable OIDC enterprise SSO connector in Sign-in Experience​

You don’t need to configure enterprise connectors individually, Logto simplifies SSO integration into your applications with just one click.

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up OIDC application on Okta admin portal​

Step 1: Create an OIDC application on Okta admin portal​

• Visit the Okta admin portal and sign in as an administrator.
• Navigate to the Applications/Applications page using the side menu.
• Click the Create App Integration button to create a new OIDC application.
• Select the OIDC - OpenID Connect option as the Sign-in method.
• Select the Web Application option as the Application type.

Click the Next button to continue.

Step 2: Configure the application settings​

1. Provide an App integration name. It will be used as the identifier of your OIDC application.
2. Add a new Sign-in redirect URIs using the Logto SSO connector's callback URL.

This is the URI that the Okta will redirect the user's browser after successful authentication. After a user successfully authenticates with the IdP, the IdP redirects the user's browser back to this designated URI along with an authorization code. Logto will complete the authentication process based on the authorization code received from this URI.

3. Assign users to the application.

Based on the Assignments settings, you can choose to assign the application to all users or specific users/groups.

Click the Save button to save the application settings.

Step 3: Set up Logto connector with the client credentials​

After successfully creating the OIDC application, you will be redirected to the application details page.

Copy the client ID and client secret and fill in the corresponding fields on the Logto SSO connector Connection tab.

Use your Okta domain as the issuer. Example: https://dev-12345678.okta.com. Once you have filled in all the fields, click the Save button to save the connector settings.

If the issuer link you provided is valid, you will see a parsed full list of Okta IdP configurations shown below the issuer field.

Step 4: Additional scopes (Optional)​

Scopes define the permissions your app requests from users and control which data your app can access from their Okta accounts. Requesting additional Okta permissions requires configuration on both sides:

In Okta admin console:

1. Navigate to Applications > Applications and select your OIDC application.
2. Go to the Assignments tab to ensure your app has access to the required users and groups.
3. For custom scopes, navigate to Security > API > Authorization Servers and select your authorization server.
4. Add custom scopes if needed:
   • Click Scopes and then Add Scope
   • Define scope names like okta.users.read or okta.groups.read for accessing Okta APIs
   • Configure consent requirements for each scope

For a complete list of available scopes and their descriptions, please refer to the Okta OIDC documentation.

In Logto Okta connector:

1. Logto automatically includes openid, profile, and email scopes to retrieve basic user identity information. You can leave the Scopes field blank if you only need basic user information.
2. Add offline_access to the Scopes field if you plan to store tokens for persistent API access. This scope enables refresh tokens for long-lived API access.
3. Add additional scopes (separated by spaces) in the Scopes field to request more data from Okta. For example: okta.users.read okta.groups.read

Step 5: Store tokens to access Okta APIs (Optional)​

If you want to access Okta scopes and perform actions with user authorization, Logto needs to get specific scopes and store tokens.

1. Add the required scopes in your Okta developer console API permissions configuration and Logto Okta connector.
2. Enable Store tokens for persistent API access in Logto Okta connector. Logto will securely store Okta access and refresh tokens in the Secret Vault.
3. To ensure refresh tokens are returned, add the offline_access scope to your Okta application permissions and include it in your Logto Okta connector scopes. This scope allows your application to maintain access to resources for extended periods.

Step 6: Set email domains and enable the SSO connector​

Provide the email domains of your organization on Logto's connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use your SSO connector as their only authentication method.

1. Run your application, you will see the sign-in button.
2. Click the sign-in button, the SDK will init the sign-in process and redirect you to the Logto sign-in page.
3. After you signed in, you will be redirected back to your application and see the sign-out button.
4. Click the sign-out button to clear token storage and sign out.

Add SAML enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with iOS (Swift) as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up SAML SSO application on your IdP​

Step 1: Create a SAML SSO application on your IdP {#step-1-create-a-saml-sso-application-on-your-idp}

Initiate the SAML SSO integration by creating an application on the IdP side. Obtain the following configurations from Logto, representing your Service Provider (SP):

• Audience URI(SP Entity ID): It represents as a globally unique identifier for your Logto service, functioning as the EntityId for SP during authentication requests to the IdP. This identifier is pivotal for the secure exchange of SAML assertions and other authentication-related data between the IdP and Logto.
• ACS URL: The Assertion Consumer Service (ACS) URL is the location where the SAML assertion is sent with a POST request. This URL is used by the IdP to send the SAML assertion to Logto. It acts as a callback URL where Logto expects to receive and consume the SAML response containing the user's identity information.

Fill in the Audience URI and ACS URL configurations in your IdP SAML application and continue to retrieve the following configurations from your IdP.

Step 2: Configure SAML SSO on Logto​

To make the SAML SSO integration work, you will need to provide the IdP metadata to Logto. The IdP metadata is an XML document that contains all the information required for Logto to establish the trust with the IdP.

Navigate to the Connection tab. Logto provides three different ways to configure the IdP metadata:

1. Metadata URL: Provide the URL of the IdP metadata XML document. Logto will fetch the metadata from the URL and configure the SAML SSO integration automatically.
2. Upload Metadata: Upload the IdP metadata XML document. Logto will parse the XML document and configure the SAML SSO integration automatically.
3. Manual Configuration: Manually configure the IdP metadata.

• IdP entity ID: The Entity ID of the IdP.
• Single sign-on URL: The URL of the IdP Single Sign-On Service.
• Signing certificate: The x509 certificate is used to verify the signature of the SAML response from the IdP.

With either of the above configurations, Logto will parse the IdP metadata and configure the SAML SSO integration accordingly.

Step 3: Configure user attributes mapping​

The user attributes returned from IdP may vary depending on the IdP configuration. Logto provides a flexible way to map the user attributes returned from IdP to the user attributes in Logto. You can configure the user attributes mapping in the SAML SSO integration experience tab.

• id: The unique identifier of the user. Logto will read the nameId claim from the SAML response as the user SSO identity id.
• email: The email address of the user.
• name: The name of the user.

Step4: Set email domains and enable the SSO connector​

Provide the email domains of your organization in Logto’s connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use the SAML SSO connector as their only authentication method.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the SAML enterprise SSO connector should be available now.

Enable SAML enterprise SSO connector in Sign-in Experience​

You don’t need to configure enterprise connectors individually, Logto simplifies SSO integration into your applications with just one click.

1. Navigate to: Console > Sign-in & account > Sign-up and sign-in.
2. Enable the "Enterprise SSO" toggle.
3. Save changes.

Once enabled, a "Single Sign-On" button will appear on your sign-in page. Enterprise users with SSO-enabled email domains can access your services using their enterprise identity providers (IdPs).

To learn more about the SSO user experience, including SP-initiated SSO and IdP-initiated SSO, refer to User flows: Enterprise SSO.

Testing and Validation​

Return to your iOS (Swift) app. You should now be able to sign in with SAML enterprise SSO. Enjoy!

In this article, we will go through the steps to quickly build the Google Workspace enterprise SSO sign-in experience (user authentication) with Vanilla JS and Logto.

Prerequisites

• A running Logto instance. Check out the introduction page to get started.
• Basic knowledge of Vanilla JS.
• A usable Google Workspace enterprise SSO account.

Create an application in Logto​

Logto is based on OpenID Connect (OIDC) authentication and OAuth 2.0 authorization. It supports federated identity management across multiple applications, commonly called Single Sign-On (SSO).

To create your Single page app application, simply follow these steps:

1. Open the Logto Console. In the "Get started" section, click the "View all" link to open the application frameworks list. Alternatively, you can navigate to Logto Console > Applications, and click the "Create application" button.
2. In the opening modal, click the "Single page app" section or filter all the available "Single page app" frameworks using the quick filter checkboxes on the left. Click the "Vanilla JS" framework card to start creating your application.
3. Enter the application name, e.g., "Bookstore," and click "Create application".

🎉 Ta-da! You just created your first application in Logto. You'll see a congrats page which includes a detailed integration guide. Follow the guide to see what the experience will be in your application.

Integrate Vanilla JS with Logto​

Installation​

Choose your favorite package manager or use the CDN to install the Logto Browser SDK.

npm i @logto/browser

pnpm add @logto/browser

yarn add @logto/browser

<!-- Special thanks to jsdelivr -->
<script type="module">
  import LogtoClient from 'https://cdn.jsdelivr.net/npm/@logto/browser@2.2.13/+esm';
</script>

Init LogtoClient​

Import and init a LogtoClient instance by passing config:

import LogtoClient from '@logto/browser';

const logtoClient = new LogtoClient({
  endpoint: '<your-logto-endpoint>',
  appId: '<your-application-id>',
});

The endpoint and appId can be found in the application details page in Logto Console.

Implement a sign-in and sign-out​

Configure redirect URIs​

Before we dive into the details, here's a quick overview of the end-user experience. The sign-in process can be simplified as follows:

1. Your app invokes the sign-in method.
2. The user is redirected to the Logto sign-in page. For native apps, the system browser is opened.
3. The user signs in and is redirected back to your app (configured as the redirect URI).

Configure redirect URIs​

Switch to the application details page of Logto Console. Add a redirect URI http://localhost:3000/callback.

Just like signing in, users should be redirected to Logto for signing out of the shared session. Once finished, it would be great to redirect the user back to your website. For example, add http://localhost:3000/ as the post sign-out redirect URI section.

Then click "Save" to save the changes.

Handle redirect​

There are still things to do after the user is redirected back to your application from Logto. Let's handle it properly.

const callbackHandler = async (logtoClient) => {
  await logtoClient.handleSignInCallback(window.location.href);

  if (!logtoClient.isAuthenticated) {
    // Handle failed sign-in
    alert('Failed to sign in');
    return;
  }

  // Handle successful sign-in
  window.location.assign('/');
};

Implement sign-in and sign-out​

logtoClient provides signIn and signOut methods to help you easily manage the authentication flow.

const isAuthenticated = await logtoClient.isAuthenticated();

const onClickSignIn = () => {
  logtoClient.signIn('http://localhost:3000/callback');
};
const onClickSignOut = () => {
  logtoClient.signOut('http://localhost:3000');
};

const button = document.createElement('button');
button.innerHTML = isAuthenticated ? 'Sign Out' : 'Sign In';
button.addEventListener('click', isAuthenticated ? onClickSignOut : onClickSignIn);

document.body.appendChild(button);

Calling .signOut() will clear all the Logto data in memory and localStorage if they exist.

Handle authentication status​

In Logto SDK, generally we can use logtoClient.isAuthenticated to check the authentication status, if the user is signed in, the value will be true, otherwise, the value will be false.

In your vanilla JS app, you can use the isAuthenticated status to programmatically show and hide the sign-in and sign-out buttons. Let's see how to do it.

const redirectUrl = 'http://localhost:3000/callback';
const baseUrl = 'http://localhost:3000';

// Conditional rendering of sign-in and sign-out buttons
const render = async (logtoClient) => {
  const isAuthenticated = await logtoClient.isAuthenticated();
  const container = document.querySelector('#container');

  const onClickSignIn = () => logtoClient.signIn(redirectUrl);
  const onClickSignOut = () => logtoClient.signOut(baseUrl);

  const button = document.createElement('button');
  button.innerHTML = isAuthenticated ? 'Sign Out' : 'Sign In';
  button.addEventListener('click', isAuthenticated ? onClickSignOut : onClickSignIn);

  container.append(button);
};

Checkpoint: Test your application​

Now, you can test your application:

1. Run your application, you will see the sign-in button.
2. Click the sign-in button, the SDK will init the sign-in process and redirect you to the Logto sign-in page.
3. After you signed in, you will be redirected back to your application and see the sign-out button.
4. Click the sign-out button to clear token storage and sign out.

Add Google Workspace enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with Vanilla JS as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up Google Cloud Platform​

Step 1: Create a new project on Google Cloud Platform​

Before you can use Google Workspace as an authentication provider, you must set up a project in the Google API Console to obtain OAuth 2.0 credentials, If you already have a project, you can skip this step. Otherwise, create a new project under your Google organization.

Step 2: Config the consent screen for your application​

In order to create a new OIDC credential, you need to configure the consent screen for your application.

1. Navigate to the OAuth consent screen page and select the Internal user type. This will make the OAuth application only available to users within your organization.

2. Fill in the Consent Screen settings following the instructions on the page. You need to provide the following minimum information:

• Application name: The name of your application. It will be displayed on the consent screen.
• Support email: The support email of your application. It will be displayed on the consent screen.

3. Set the Scopes for your application. In order to retrieve the user's identity information and email address properly from the IdP, Logto SSO connectors need to grant the following scopes from the IdP:

• openid: This scope is required for OIDC authentication. It is used to retrieve the ID token and get access to the userInfo endpoint of the IdP.
• profile: This scope is required for accessing the user's basic profile information.
• email: This scope is required for accessing the user's email address.

Click the Save button to save the consent screen settings.

Step 3: Create a new OAuth credential​

Navigate to the Credentials page and click the Create Credentials button. Select the OAuth client ID option from the dropdown menu to create a new OAuth credential for your application.

Continue setting up the OAuth credential by filling up the following information:

1. Select the Web application as the application type.
2. Fill in the Name of your client application, Logto SSO Connector for example. This will help you to identify the credentials in the future.
3. Fill in the Authorized redirect URIs with the Logto callback URI. This is the URI that Google will redirect the user's browser after successful authentication. After a user successfully authenticates with the IdP, the IdP redirects the user's browser back to this designated URI along with an authorization code. Logto will complete the authentication process based on the authorization code received from this URI.
4. Fill in the Authorized JavaScript origins with the Logto callback URI's origin. This ensures only your Logto application can send requests to the Google OAuth server.
5. Click the Create button to create the OAuth credential.

Step 4: Set up Logto connector with the client credentials​

After successfully creating the OAuth credential, you will receive a prompt modal with the client ID and client secret.

Copy the Client ID and Client secret and fill in the corresponding fields on Logto’s SSO connector Connection tab.

Now you have successfully configured a Google Workspace SSO connector on Logto.

Step 5: Additional Scopes (Optional)​

Scopes define the permissions your app requests from users and control which data your app can access from their Google Workspace accounts. Requesting Google permissions requires configuration on both sides:

In Google Cloud Console:

1. Navigate to APIs & Services > OAuth consent screen > Scopes.
2. Click Add or Remove Scopes and select only the scopes your app requires:
   • Authentication (Required):
     • https://www.googleapis.com/auth/userinfo.email
     • https://www.googleapis.com/auth/userinfo.profile
     • openid
   • API access (Optional): Add any additional scopes needed for your app (e.g., Drive, Calendar, YouTube). Browse the Google API Library to find available services. If your app needs access to Google APIs beyond basic permissions, first enable the specific APIs your app will use (e.g., Google Drive API, Gmail API, Calendar API) in the Google API Library.
3. Click Update to confirm the selection.
4. Click Save and Continue to apply the changes.

In Logto Google Workspace connector:

1. Logto automatically includes openid, profile, and email scopes to retrieve basic user identity information. You can leave the Scopes field blank if you only need basic user information
2. Add additional scopes (separated by spaces) in the Scopes field to request more data from Google. Use full scope URLs, for example: https://www.googleapis.com/auth/calendar.readonly

Step 6: Store tokens to access Google APIs (Optional)​

If you want to access Google APIs and perform actions with user authorization, Logto needs to get specific API scopes and store tokens.

1. Add the required scopes in your Google Cloud Console OAuth consent screen configuration and Logto Google connector.
2. Enable Store tokens for persistent API access in Logto Google connector. Logto will securely store Google access and refresh tokens in the Secret Vault.
3. To ensure refresh tokens are returned, configure your Logto Google connector to enable Offline Access.

Step 7: Set email domains and enable the SSO connector​

Provide the email domains of your organization on Logto’s connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use your SSO connector as their only authentication method.

For more information about the Google Workspace SSO connector, please check Google OpenID Connector.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the Google Workspace enterprise SSO connector should be available now.

Enable Google Workspace enterprise SSO connector in Sign-in Experience​

You don’t need to configure enterprise connectors individually, Logto simplifies SSO integration into your applications with just one click.

1. Navigate to: Console > Sign-in & account > Sign-up and sign-in.
2. Enable the "Enterprise SSO" toggle.
3. Save changes.

Once enabled, a "Single Sign-On" button will appear on your sign-in page. Enterprise users with SSO-enabled email domains can access your services using their enterprise identity providers (IdPs).

To learn more about the SSO user experience, including SP-initiated SSO and IdP-initiated SSO, refer to User flows: Enterprise SSO.

    // Handle failed sign-in
    alert('Failed to sign in');
    return;
  }

  // Handle successful sign-in
  window.location.assign('/');
};

Add Microsoft Entra ID OIDC enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with Vanilla JS as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up Azure AD SSO application​

Step 1: Create an Microsoft EntraID OIDC application​

1. Go to the Microsoft Entra admin center and sign in as an administrator.

2. Browse to Identity > Applications > App registrations.

3. Select New registration.

4. Enter the application name and select the appropriate account type for your application.

5. Select Web as the application platform.

6. Copy and paste the redirect URI from Logto's SSO settings page. The redirect URI is the URL where the user is redirected after they have authenticated with Microsoft Entra ID.

6. Click Register to create the application.

Step 2: Configure Microsoft Entra ID OIDC SSO at Logto​

After successfully creating an Microsoft Entra OIDC application, you will need to provide the IdP configurations back to Logto. Navigate to the Connection tab at Logto Console, and fill in the following configurations:

1. Client ID: A unique identifier assigned to your OIDC application by the Microsoft Entra. This identifier is used by Logto to identify and authenticate the application during the OIDC flow. You can find it in the application overview page as Application (client) ID.

2. Client Secret: Create a new client secret and copy the value to Logto. This secret is used to authenticate the OIDC application and secure the communication between Logto and the IdP.

3. Issuer: The issuer URL, a unique identifier for the IdP, specifying the location where the OIDC identity provider can be found. It is a crucial part of the OIDC configuration as it helps Logto discover the necessary endpoints.

   Instead of manually provide all these OIDC endpoints, Logto fetch all the required configurations and IdP endpoints automatically. This is done by utilizing the issuer url you provided and making a call to the IdP's discover endpoint.

   To get the issuer URL, you can find it in the Endpoints section of the application overview page.

   Locate the OpenID Connect metadata document endpoint and copy the URL WITHOUT the trailing path .well-known/openid-configuration. This is because Logto will automatically append the .well-known/openid-configuration to the issuer URL when fetching the OIDC configurations.

4. Scope (Optional): Logto automatically includes the required scopes (openid, profile, and email) in all requests. You can specify additional scopes as a space-separated list if your application requires extra permissions or access levels from the IdP.

Click Save to finish the configuration process

Step 3: Additional scopes (Optional)​

Scopes define the permissions your app requests from users and control which data your app can access from their Microsoft Entra ID accounts. Requesting Microsoft Graph permissions requires configuration on both sides:

In Microsoft Entra admin center:

1. Navigate to Microsoft Entra ID > App registrations and select your application.
2. Go to API permissions > Add a permission > Microsoft Graph > Delegated permissions.
3. Select only the permissions your app requires:
   • OpenID permissions:
     • openid (Required) - Sign users in
     • profile (Required) - View users' basic profile
     • email (Required) - View users' email address
     • offline_access (Optional) - Required only if you enable Store tokens for persistent API access in the Logto connector and need to obtain refresh tokens for long-lived access to Microsoft Graph APIs.
   • API access (Optional): Add any additional permissions needed for your app. Common Microsoft Graph permissions include Mail.Read, Calendars.Read, Files.Read, etc. Browse the Microsoft Graph permissions reference to find available permissions.
4. Click Add permissions to confirm the selection.
5. If your app requires admin consent for certain permissions, click Grant admin consent for [Your Organization].

In Logto Microsoft Entra ID connector:

1. Logto automatically includes openid, profile, and email scopes to retrieve basic user identity information. You can leave the Scopes field blank if you only need basic user information.
2. Add offline_access to the Scopes field if you plan to store tokens for persistent API access. This scope enables refresh tokens for long-lived API access.
3. Add additional scopes (separated by spaces) in the Scopes field to request more data from Microsoft Graph. Use standard scope names, for example: User.Read Mail.Read Calendars.Read

Step 4: Store tokens to access Microsoft APIs (Optional)​

If you want to access Microsoft Graph APIs and perform actions with user authorization, Logto needs to get specific API scopes and store tokens.

1. Add the required scopes in your Microsoft Entra admin center API permissions configuration and Logto Microsoft Entra ID connector.
2. Enable Store tokens for persistent API access in Logto Microsoft Entra ID connector. Logto will securely store Microsoft access and refresh tokens in the Secret Vault.
3. To ensure refresh tokens are returned, add the offline_access scope to your Microsoft Entra ID application permissions and include it in your Logto Microsoft Entra ID connector scopes. This scope allows your application to maintain access to resources for extended periods.

Step 5: Set email domains and enable the SSO connector​

Provide the email domains of your organization on the connector experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be exclusively limited to use your SSO connector as their only authentication method.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the Microsoft Entra ID OIDC enterprise SSO connector should be available now.

Enable Microsoft Entra ID OIDC enterprise SSO connector in Sign-in Experience​

In this article, we will go through the steps to quickly build the Microsoft Entra ID SAML enterprise SSO sign-in experience (user authentication) with Vanilla JS and Logto.

Prerequisites

• A running Logto instance. Check out the introduction page to get started.
• Basic knowledge of Vanilla JS.
• A usable Microsoft Entra ID SAML enterprise SSO account.

Create an application in Logto​

Logto is based on OpenID Connect (OIDC) authentication and OAuth 2.0 authorization. It supports federated identity management across multiple applications, commonly called Single Sign-On (SSO).

To create your Single page app application, simply follow these steps:

1. Open the Logto Console. In the "Get started" section, click the "View all" link to open the application frameworks list. Alternatively, you can navigate to Logto Console > Applications, and click the "Create application" button.
2. In the opening modal, click the "Single page app" section or filter all the available "Single page app" frameworks using the quick filter checkboxes on the left. Click the "Vanilla JS" framework card to start creating your application.
3. Enter the application name, e.g., "Bookstore," and click "Create application".

🎉 Ta-da! You just created your first application in Logto. You'll see a congrats page which includes a detailed integration guide. Follow the guide to see what the experience will be in your application.

Integrate Vanilla JS with Logto​

Installation​

Choose your favorite package manager or use the CDN to install the Logto Browser SDK.

npm i @logto/browser

pnpm add @logto/browser

yarn add @logto/browser

<!-- Special thanks to jsdelivr -->
<script type="module">
  import LogtoClient from 'https://cdn.jsdelivr.net/npm/@logto/browser@2.2.13/+esm';
</script>

Init LogtoClient​

Import and init a LogtoClient instance by passing config:

import LogtoClient from '@logto/browser';

const logtoClient = new LogtoClient({
  endpoint: '<your-logto-endpoint>',
  appId: '<your-application-id>',
});

The endpoint and appId can be found in the application details page in Logto Console.

Implement a sign-in and sign-out​

Configure redirect URIs​

Before we dive into the details, here's a quick overview of the end-user experience. The sign-in process can be simplified as follows:

1. Your app invokes the sign-in method.
2. The user is redirected to the Logto sign-in page. For native apps, the system browser is opened.
3. The user signs in and is redirected back to your app (configured as the redirect URI).

Configure redirect URIs​

Switch to the application details page of Logto Console. Add a redirect URI http://localhost:3000/callback.

Just like signing in, users should be redirected to Logto for signing out of the shared session. Once finished, it would be great to redirect the user back to your website. For example, add http://localhost:3000/ as the post sign-out redirect URI section.

Then click "Save" to save the changes.

Handle redirect​

There are still things to do after the user is redirected back to your application from Logto. Let's handle it properly.

const callbackHandler = async (logtoClient) => {
  await logtoClient.handleSignInCallback(window.location.href);

  if (!logtoClient.isAuthenticated) {
    // Handle failed sign-in
    alert('Failed to sign in');
    return;
  }

  // Handle successful sign-in
  window.location.assign('/');
};

Implement sign-in and sign-out​

logtoClient provides signIn and signOut methods to help you easily manage the authentication flow.

const isAuthenticated = await logtoClient.isAuthenticated();

const onClickSignIn = () => {
  logtoClient.signIn('http://localhost:3000/callback');
};
const onClickSignOut = () => {
  logtoClient.signOut('http://localhost:3000');
};

const button = document.createElement('button');
button.innerHTML = isAuthenticated ? 'Sign Out' : 'Sign In';
button.addEventListener('click', isAuthenticated ? onClickSignOut : onClickSignIn);

document.body.appendChild(button);

Calling .signOut() will clear all the Logto data in memory and localStorage if they exist.

Handle authentication status​

In Logto SDK, generally we can use logtoClient.isAuthenticated to check the authentication status, if the user is signed in, the value will be true, otherwise, the value will be false.

In your vanilla JS app, you can use the isAuthenticated status to programmatically show and hide the sign-in and sign-out buttons. Let's see how to do it.

const redirectUrl = 'http://localhost:3000/callback';
const baseUrl = 'http://localhost:3000';

// Conditional rendering of sign-in and sign-out buttons
const render = async (logtoClient) => {
  const isAuthenticated = await logtoClient.isAuthenticated();
  const container = document.querySelector('#container');

  const onClickSignIn = () => logtoClient.signIn(redirectUrl);
  const onClickSignOut = () => logtoClient.signOut(baseUrl);

  const button = document.createElement('button');
  button.innerHTML = isAuthenticated ? 'Sign Out' : 'Sign In';
  button.addEventListener('click', isAuthenticated ? onClickSignOut : onClickSignIn);

  container.append(button);
};

Checkpoint: Test your application​

Now, you can test your application:

1. Run your application, you will see the sign-in button.
2. Click the sign-in button, the SDK will init the sign-in process and redirect you to the Logto sign-in page.
3. After you signed in, you will be redirected back to your application and see the sign-out button.
4. Click the sign-out button to clear token storage and sign out.

Add Microsoft Entra ID SAML enterprise SSO connector​

To simplify access management and gain enterprise-level safeguards for your big clients, connect with Vanilla JS as a federated identity provider. The Logto enterprise SSO connector helps you establish this connection in minutes by allowing several parameter inputs.

To add an enterprise SSO connector, simply follow these steps:

1. Navigate to Logto console > Enterprise SSO.

2. Click "Add enterprise connector" button and choose your SSO provider type. Choose from prebuilt connectors for Microsoft Entra ID (Azure AD), Google Workspace, and Okta, or create a custom SSO connection using the standard OpenID Connect (OIDC) or SAML protocol.
3. Provide a unique name (e.g., SSO sign-in for Acme Company).

4. Configure the connection with your IdP in the "Connection" tab. Check the guides above for each connector types.

5. Customize the SSO experience and enterprise’s email domain in the "Experience" tab. Users sign in with the SSO-enabled email domain will be redirected to SSO authentication.

6. Save changes.

Set up Azure AD SSO application​

Step 1: Create an Azure AD SSO application​

Initiate the Azure AD SSO integration by creating an SSO application on the Azure AD side.

1. Go to the Azure portal and sign in as an administrator.
2. Select Microsoft Entra ID service.
3. Navigate to the Enterprise applications using the side menu. Click New application, and select Create your own application.

1. Enter the application name and select Integrate any other application you don't find in the gallery (Non-gallery).
2. Select Setup single sign-on > SAML.

1. Follow the instructions, as the first step, you will need to fill in the basic SAML configuration using the following information provided by Logto.

• Audience URI(SP Entity ID): It represents as a globally unique identifier for your Logto service, functioning as the EntityId for SP during authentication requests to the IdP. This identifier is pivotal for the secure exchange of SAML assertions and other authentication-related data between the IdP and Logto.
• ACS URL: The Assertion Consumer Service (ACS) URL is the location where the SAML assertion is sent with a POST request. This URL is used by the IdP to send the SAML assertion to Logto. It acts as a callback URL where Logto expects to receive and consume the SAML response containing the user's identity information.

Click Save to continue.

Step 2: Configure SAML SSO at Logto​

To make the SAML SSO integration work, you will need to provide the IdP metadata back to Logto. Let's switch back to the Logto side, and navigate to the Connection tab of your Azure AD SSO connector.

Logto provides three different ways to configure the IdP metadata. The easiest way is by providing the metadata URL of the Azure AD SSO application.

Copy the App Federation Metadata Url from your Azure AD SSO application's SAML Certificates section and paste it into the Metadata URL field in Logto.

Logto will fetch the metadata from the URL and configure the SAML SSO integration automatically.

Step 3: Configure user attributes mapping​

Logto provides a flexible way to map the user attributes returned from IdP to the user attributes in Logto. Logto will sync the following user attributes from IdP by default:

• id: The unique identifier of the user. Logto will read the nameID claim from the SAML response as the user SSO identity id.
• email: The email address of the user. Logto will read the email claim from the SAML response as the user primary email by default.
• name: The name of the user.

You may manage the user attributes mapping logic either on the Azure AD side or Logto side.

1. Map the AzureAD user attributes to Logto user attributes on Logto side.

   Visit the Attributes & Claims section of your Azure AD SSO application.

   Copy the following attribute names (with namespace prefix) and paste them into the corresponding fields in Logto.

   • http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress
   • http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name (Recommendation: update this attribute value map to user.displayname for better user experience)a

1. Map the AzureAD user attributes to Logto user attributes at the AzureAD side.

   Visit the Attributes & Claims section of your Azure AD SSO application.

   Click on Edit, and update the Additional claims fields based on the Logto user attributes settings:

   • update the claim name value based on the Logto user attributes settings.
   • remove the namespace prefix.
   • click Save to continue.

   Should end up with the following settings:

You may also specify additional user attributes on the Azure AD side. Logto will keep a record of the original user attributes returned from IdP under the user's sso_identity field.

Step 4: Assign users to the Azure AD SSO application​

Visit the Users and groups section of your Azure AD SSO application. Click on Add user/group to assign users to the Azure AD SSO application. Only users assigned to your Azure AD SSO application will be able to authenticate through the Azure AD SSO connector.

Step 5: Set email domains and enable the SSO connector​

Provide the email domains of your organization at Logto's connector SSO experience tab. This will enable the SSO connector as an authentication method for those users.

Users with email addresses in the specified domains will be redirected to use the SAML SSO connector as their only authentication method.

Please check Azure AD's official documentation for more details about the Azure AD SSO integration.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the Microsoft Entra ID SAML enterprise SSO connector should be available now.

Enable Microsoft Entra ID SAML enterprise SSO connector in Sign-in Experience​

You don’t need to configure enterprise connectors individually, Logto simplifies SSO integration into your applications with just one click.

1. Navigate to: Console > Sign-in & account > Sign-up and sign-in.
2. Enable the "Enterprise SSO" toggle.
3. Save changes.

Once enabled, a "Single Sign-On" button will appear on your sign-in page. Enterprise users with SSO-enabled email domains can access your services using their enterprise identity providers (IdPs).

To learn more about the SSO user experience, including SP-initiated SSO and IdP-initiated SSO, refer to User flows: Enterprise SSO.

Testing and Validation​

Return to your Vanilla JS app. You should now be able to sign in with Microsoft Entra ID SAML enterprise SSO. Enjoy!
