EasyAuth Client Plugin

This guide is for a developer who has never wired SSO before. Follow the steps exactly.

Overview

Step 1: Create a client on the EasyAuth server

1. Log in to the EasyAuth admin panel.
2. Create a new OAuth client.
3. Copy the Client ID and Client Secret.
4. Add your app’s callback URL. Example:
   • https://your-app.test/auth/callback

The callback URL is provided by this package (it’s always your APP_URL + the callback route). You can also print it by running php artisan easyauth:install --publish.

You need these values for your app’s .env in Step 4.

Step 2: Install the plugin in your app

Run this in your Laravel/Filament app:

This adds the routes and publishes the config file.

Step 3: Ensure your app has sessions enabled

The plugin uses sessions to store the OAuth state, tokens, and login status. Make sure:

• Your app uses the web middleware group.
• SESSION_DRIVER is set (database or file both work).

Step 4: Add the EasyAuth settings to your .env

Use the values from Step 1:

Everything else can be configured in config/easyauth.php (published in Step 2).

Step 5: Send users to /auth/login

This route is provided by the plugin. Example:

• Add a “Sign in with EasyAuth” button that links to /auth/login.

When a user visits /auth/login, the plugin redirects them to:

• https://auth.example.com/oauth/authorize?client_id=...&redirect_uri=...

Optional: use the built-in "Continue with Easy Auth" button

The plugin provides a Blade component you can drop into any Blade view:

This renders a branded button linking to route('sso.login').

Optional: override your app's login route

If you want /login (or other paths) to redirect into the EasyAuth flow, enable route overrides in config/easyauth.php:

Step 6: What happens on callback (automatic)

After login, EasyAuth redirects back to your callback URL with a code.

The plugin does this automatically:

1. Exchanges the code for tokens at /oauth/token.
2. Calls /api/oauth/userinfo to fetch the user profile.
3. Finds or creates a local user.
4. Logs the user into your app.
5. Redirects to the intended URL, falling back to easyauth.post_login_redirect.

You do not need to write this logic yourself.

Step 7: Logout

POST /auth/logout to:

1. Log out locally.
2. Redirect the user to EasyAuth logout.

Routes provided by the plugin

• /auth/login: start SSO
• /auth/callback: complete SSO (implemented by the plugin)
• /auth/refresh: refresh tokens
• /auth/logout: log out
• /auth/error: error screen

User mapping (when the user does not exist locally)

The plugin creates a local user using:

• EASYAUTH_USER_IDENTIFIER (default: email)
• EASYAUTH_NAME_ATTRIBUTE (default: name)
• EASYAUTH_EMAIL_ATTRIBUTE (default: email)

If your users are matched by another field, set those keys in .env.

Common issues and fixes

• Redirect URI mismatch: the callback URL must exactly match what you registered.
• Invalid state: user opened the callback in a different browser or session expired.
• Userinfo failed: make sure the userinfo endpoint is reachable and scopes include openid.
