For our new friends:

Logto is an Auth0 alternative designed for modern apps and SaaS products. It offers both Cloud and Open-source services to help you quickly launch your identity and management (IAM) system. Enjoy authentication, authorization, and multi-tenant management all in one.

We recommend starting with a free development tenant on Logto Cloud. This allows you to explore all the features easily.

In this article, we will go through the steps to quickly build the GitHub sign-in experience (user authentication) with WordPress plugin and Logto.

Prerequisites

• A running Logto instance. Check out the introduction page to get started.
• Basic knowledge of WordPress plugin.
• A usable GitHub 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 Traditional web 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 "Traditional web" section or filter all the available "Traditional web" frameworks using the quick filter checkboxes on the left. Click the "WordPress" 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 WordPress with Logto

Install the plugin

From WordPress admin panel

1. Go to Plugins > Add New.
2. Search for "Logto", or enter https://wordpress.org/plugins/logto/ in the search box.
3. Click Install Now.
4. Click Activate.

From upload

1. Download the Logto WordPress plugin from one of the following links:
   • Latest release: Download the file which name in the format of logto-plugin-<version>.zip.
   • WordPress plugin directory: Download the file by clicking the Download button.
2. Download the plugin ZIP file.
3. Go to Plugins > Add New in your WordPress admin panel.
4. Click Upload Plugin.
5. Select the downloaded ZIP file and click Install Now.
6. Click Activate.

Configure the plugin

Now you should be able to see the Logto menu in your WordPress admin panel sidebar. Click Logto > Settings to configure the plugin.

note:

You should have a traditional web application created in Logto Console before configuring the plugin. If you haven't created one, please refer to Integrate Logto into your application for more information.

The minimum configuration to get started for the plugin is:

• Logto endpoint: The endpoint of your Logto tenant.
• App ID: The app ID of your Logto application.
• App secret: One of the valid app secrets of your Logto application.

All values can be found on the application details page in Logto Console.

After filling in the values, click Save Changes (scroll down to the bottom of the page if you can't find the button).

Configure redirect URI

The redirect URI is the URL to which Logto will redirect users after they have authenticated; and the post sign-out redirect URI is the URL to which Logto will redirect users after they have logged out.

Here's a non-normative sequence diagram to illustrate the sign-in flow:

Here's how the sign-out flow looks like in a non-normative sequence diagram:

To learn more about why redirect is needed, see Sign-in experience explained.

In our case, we need to configure both redirect URIs in your Logto Console. To find the redirect URI, go to the Logto > Settings page in your WordPress admin panel. You'll see the Redirect URI and Post sign-out redirect URI fields.

1. Copy the Redirect URI and Post sign-out redirect URI values and paste them into the Redirect URIs and Post sign-out redirect URIs fields in your Logto Console.
2. Click Save changes in Logto Console.

Checkpoint: Test your WordPress website

Now you can test your Logto integration in your WordPress website:

1. Open an incognito browser window if needed.
2. Visit your WordPress website and click the Log in link if applicable; or directly visit the login page (e.g., https://example.com/wp-login.php).
3. The page should redirect you to the Logto sign-in page.
4. Complete the sign-in or sign-up process.
5. After successful authentication, you should be redirected back to your WordPress website and logged in automatically.
6. Click the Log out link to log out of your WordPress website.
7. You should be redirected to the Logto sign-out page, then back to your WordPress website.
8. You should be logged out of your WordPress website.

To learn more about the WordPress plugin settings, see WordPress quick start.

Add GitHub connector

To enable quick sign-in and improve user conversion, connect with WordPress as an identity provider. The Logto social connector helps you establish this connection in minutes by allowing several parameter inputs.

To add a social connector, simply follow these steps:

1. Navigate to Console > Connectors > Social Connectors.
2. Click "Add social connector" and select "GitHub".
3. Follow the README guide and complete required fields and customize settings.

note:

If you are following the in-place Connector guide, you can skip the next section.

Set up GitHub OAuth app

Step 1: Create an OAuth app on GitHub

Before you can use GitHub as an authentication provider, you must create an OAuth App on GitHub to obtain OAuth 2.0 credentials.

1. Go to GitHub and sign in with your account, or create a new account if needed.
2. Navigate to Settings > Developer settings > OAuth apps.
3. Click New OAuth App to register a new application:
   • Application name: Enter a descriptive name for your app.
   • Homepage URL: Enter your application's homepage URL.
   • Authorization callback URL: Copy the Callback URI from your Logto GitHub connector and paste it here. After users sign in with GitHub, they'll be redirected here with an authorization code that Logto uses to complete authentication.
   • Application description: (Optional) Add a brief description of your app.
4. Click Register application to create the OAuth App.

note:

We suggest not checking the box for Enable Device Flow, as users who sign in with GitHub on mobile devices would need to confirm the initial sign-in action in the GitHub mobile app. Many GitHub users do not install the GitHub mobile app on their phones, which could block the sign-in flow. Only enable this if you expect end-users to confirm their sign-in flow through the GitHub mobile app. See details about device flow.

For more details on setting up GitHub OAuth Apps, see Creating an OAuth App.

Step 2: Configure your Logto connector

After creating the OAuth app in GitHub, you'll be redirected to a details page where you can copy the Client ID and generate a Client secret.

1. Copy the Client ID from your GitHub OAuth app and paste it into the clientId field in Logto.
2. Click Generate a new client secret in GitHub to create a new secret, then copy and paste it into the clientSecret field in Logto.
3. Click Save and Done in Logto to connect your identity system with GitHub.

warning:

Keep your Client secret secure and never expose it in client-side code. GitHub client secrets cannot be recovered if lost - you'll need to generate a new one.

Step 3: Configure scopes (Optional)

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

Use the Scopes field in Logto to request extra permissions from GitHub. Choose one of the following approaches based on your needs:

Option 1: No extra API scopes needed

• Leave the Scopes field in your Logto GitHub connector blank.
• The default scope read:user will be requested to ensure Logto can get basic user info (e.g., email, name, avatar) properly.

Option 2: Request additional scopes at sign-in

• Browse all available GitHub scopes for OAuth apps and add only the scopes your app needs.
• Enter all desired scopes in the Scopes field, separated by spaces.
• Any scopes you list here override the defaults, so always include the authentication scope: read:user.
• Common additional scopes include:
  • repo: Full control of private repositories
  • public_repo: Access to public repositories
  • user:email: Access to user email addresses
  • notifications: Access to notifications
• Ensure all scopes are spelled correctly and valid. An incorrect or unsupported scope will result in an "Invalid scope" error from GitHub.

Option 3: Request incremental scopes later

• After the user signs in, you can request additional scopes on demand by reinitiating a federated social authorization flow and updating users' stored token set.
• These additional scopes do not need to be filled in the Scopes field in your Logto GitHub connector, and can be achieved through Logto's Social Verification API.

By following these steps, your Logto GitHub connector requests exactly the permissions your app needs - no more, no less.

tip:

If your app requests these scopes to access the GitHub API and perform actions, make sure to enable Store tokens for persistent API access in Logto GitHub connector. See the next section for details.

Step 4: General settings

Here are some general settings that won't block the connection to GitHub but may affect the end-user authentication experience.

Sync profile information

In the GitHub connector, you can set the policy for syncing profile information, such as user names and avatars. Choose from:

• Only sync at sign-up: Profile info is fetched once when the user first signs in.
• Always sync at sign-in: Profile info is updated every time the user signs in.

Store tokens to access GitHub APIs (Optional)

If you want to access GitHub APIs and perform actions with user authorization (whether via social sign-in or account linking), Logto needs to get specific API scopes and store tokens.

1. Add the required scopes following the instructions above.
2. Enable Store tokens for persistent API access in the Logto GitHub connector. Logto will securely store GitHub access tokens in the Secret Vault.

note:

When using a GitHub OAuth App as described in this tutorial, you cannot get a refresh token from GitHub because its access token does not expire unless the user manually revokes it. Therefore, you do not need to add offline_access in the Scopes field — doing so may cause an error.

If you want the access token to expire or use refresh tokens, consider integrating with a GitHub App instead. Learn about the differences between GitHub Apps and OAuth Apps.

Step 5: Test your integration (Optional)

Before going live, test your GitHub integration:

1. Use the connector in a Logto development tenant.
2. Verify that users can sign in with GitHub.
3. Check that the correct scopes are being requested.
4. Test API calls if you're storing tokens.

GitHub OAuth Apps work with any GitHub user account immediately - there's no need for test users or app approval like some other platforms.

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 GitHub connector should be available now.

Enable GitHub connector in Sign-in Experience

Once you create a social connector successfully, you can enable it as a "Continue with GitHub" button in Sign-in Experience.

1. Navigate to Console > Sign-in experience > Sign-up and sign-in.
2. (Optional) Choose "Not applicable" for sign-up identifier if you need social login only.
3. Add configured GitHub connector to the "Social sign-in" section.

Testing and Validation

Return to your WordPress plugin app. You should now be able to sign in with GitHub. Enjoy!
