Auth0 Laravel Web App Integration

Add login, logout, and user profile to a Laravel web application using auth0/login (Laravel Auth0 SDK).

When NOT to Use

Key SDK Methods

User Object

The authenticated user is a StatefulUser instance implementing Laravel's Authenticatable contract. It uses __get magic for property-style access to claims:

$user = auth()->user();

$user->name;                   // display name (via __get)
$user->email;                  // email address (via __get)
$user->picture;                // avatar URL (via __get)
$user->email_verified;         // any claim via property access
$user->getAuthIdentifier();   // Auth0 'sub' (e.g. 'auth0|abc123')
$user->getAttribute('sub');    // explicit claim access
$user->jsonSerialize();        // all claims as array

Access any ID token claim as a property: $user->nickname, $user->updated_at, $user->sub, etc. For explicit access, use $user->getAttribute('claim_name').

Quick Reference

Guard configuration (config/auth.php):

'guards' => [
    'web' => [
        'driver' => 'auth0.authenticator',
        'provider' => 'auth0-provider',
        'configuration' => 'web',
    ],
],
'providers' => [
    'auth0-provider' => [
        'driver' => 'auth0.provider',
        'repository' => 'auth0.repository',
    ],
],

Route protection:

Route::middleware('auth')->group(function () {
    Route::get('/dashboard', [DashboardController::class, 'index']);
});

Check auth in Blade:

@auth
    <p>Hello, {{ auth()->user()->name }}</p>
@else
    <a href="/login">Login</a>
@endauth

Environment variables:

• APP_URL - Application URL with port (e.g. http://localhost:8000)
• AUTH0_DOMAIN - Auth0 tenant domain (e.g. tenant.us.auth0.com)
• AUTH0_CLIENT_ID - Application client ID
• AUTH0_CLIENT_SECRET - Application client secret
• AUTH0_AUDIENCE - API identifier (required for JWT access tokens)
• AUTH0_REDIRECT_URI - Callback URL (defaults to ${APP_URL}/callback)
• APP_KEY - Laravel app key, used as cookie encryption secret

Prerequisites

• Laravel 11+ application
• PHP 8.2+ with extensions: mbstring, openssl, json
• Composer installed
• Auth0 Regular Web Application configured (not an API - must be an Application)
• If you don't have Auth0 set up yet, use the auth0-quickstart skill first

Quick Start Workflow

1. Install SDK

composer require auth0/login

The auth0/login package requires auth0/auth0-php (v8.19+) and will install it automatically. It also requires a PSR-18 HTTP client - if you don't already have one, install Guzzle:

composer require guzzlehttp/guzzle guzzlehttp/psr7

2. Publish Configuration

php artisan vendor:publish --tag=auth0

This creates config/auth0.php with guard, middleware, and route configuration.

3. Configure Environment

Add to your .env:

APP_URL=http://localhost:8000
AUTH0_DOMAIN=your-tenant.us.auth0.com
AUTH0_CLIENT_ID=your_client_id
AUTH0_CLIENT_SECRET=your_client_secret
AUTH0_AUDIENCE=https://your-api-identifier
AUTH0_REDIRECT_URI=${APP_URL}/callback

AUTH0_DOMAIN is your Auth0 tenant domain (without https://). AUTH0_CLIENT_ID and AUTH0_CLIENT_SECRET come from your Auth0 Application settings. AUTH0_AUDIENCE must be set to an API identifier registered in Auth0 (Auth0 Dashboard > Applications > APIs) - without it, Auth0 returns opaque access tokens that the SDK cannot decode, causing a crash on session restore. The SDK uses APP_KEY as the cookie secret by default - no separate secret needed.

Important: Ensure APP_URL includes the port if using the built-in dev server (http://localhost:8000). Fresh Laravel installs default to http://localhost (no port) which causes callback URL mismatches.

4. Configure Auth0 Dashboard

In your Auth0 Application settings:

• Application Type: Regular Web Application
• Allowed Callback URLs: http://localhost:8000/callback
• Allowed Logout URLs: http://localhost:8000

5. Configure Auth Guards

Update config/auth.php to use Auth0 guards:

'guards' => [
    'web' => [
        'driver' => 'auth0.authenticator',
        'provider' => 'auth0-provider',
        'configuration' => 'web',
    ],
],

'providers' => [
    'auth0-provider' => [
        'driver' => 'auth0.provider',
        'repository' => 'auth0.repository',
    ],
],

The configuration key maps to the guard definition in config/auth0.php (web uses STRATEGY_REGULAR with session-based auth). We override the default web guard so that Laravel's built-in auth middleware and auth()->user() work without specifying a guard name. The SDK also auto-registers an auth0-session guard with identical config, but overriding web is simpler.

6. Routes Are Auto-Registered

The SDK automatically registers these routes when registerAuthenticationRoutes is true in config/auth0.php:

• GET /login - Redirects to Auth0 Universal Login
• GET /callback - Handles OAuth callback, exchanges code for tokens
• GET /logout - Destroys session and redirects to Auth0 logout

No manual route definitions needed for the auth flow.

7. Add Protected Routes

In routes/web.php:

use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return view('home', ['user' => auth()->user()]);
});

Route::middleware('auth')->group(function () {
    Route::get('/profile', function () {
        return view('profile', ['user' => auth()->user()]);
    });
});

The standard auth middleware works with the Auth0 guard. Unauthenticated users are redirected to /login.

8. Create Views

Create resources/views/home.blade.php:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Home</title>
</head>
<body>
    @if($user)
        <h1>Welcome, {{ $user->name }}!</h1>
        <p><a href="/profile">Profile</a></p>
        <p><a href="/logout">Logout</a></p>
    @else
        <h1>Welcome</h1>
        <p><a href="/login">Login</a></p>
    @endif
</body>
</html>

Create resources/views/profile.blade.php:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Profile</title>
</head>
<body>
    <h1>{{ $user->name }}</h1>
    <p>Email: {{ $user->email }}</p>
    <img src="{{ $user->picture }}" alt="avatar" width="100" />
    <hr>
    <h2>User Claims</h2>
    <pre>{{ json_encode($user->jsonSerialize(), JSON_PRETTY_PRINT) }}</pre>
    <p><a href="/">Home</a> | <a href="/logout">Logout</a></p>
</body>
</html>

9. Test Authentication

php artisan serve

Visit http://localhost:8000 and click Login.

Important: Always access the app via http://localhost:8000 (not http://127.0.0.1:8000). The callback URL uses localhost, so the session cookie must be set for localhost to persist across the Auth0 login redirect. Using 127.0.0.1 causes an "Invalid state" error because the session cookie won't be sent to the localhost callback URL.
