Laravel 12 Authentication with Breeze & Sanctum (Complete Guide 2026)

Laravel 12 Authentication Tutorial: In this guide, we will implement authentication in Laravel 12 using Breeze and Sanctum. Authentication is a core feature of modern web applications, allowing users to securely register, login, and access protected resources.

Laravel Breeze provides a simple authentication system for web applications, while Sanctum is used for API authentication.

Step 1. Install Laravel 12

composer create-project laravel/laravel laravel-auth
cd laravel-auth

Step 2. Install Laravel Breeze

composer require laravel/breeze --dev
php artisan breeze:install
npm install && npm run dev
php artisan migrate

Breeze provides login, registration, password reset, and email verification features.

Step 3. Test Authentication

Run the server:

php artisan serve

Visit:

• /register
• /login

Step 4. Install Laravel Sanctum

composer require laravel/sanctum
php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"
php artisan migrate

Step 5. Configure Sanctum

Add Sanctum middleware in app/Http/Kernel.php:

'api' => [
    \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
],

Step 6. Create API Login

Route::post('/login', function (Request $request) {
    $credentials = $request->only('email', 'password');

    if (!Auth::attempt($credentials)) {
        return response()->json(['message' => 'Invalid login'], 401);
    }

    $user = Auth::user();
    $token = $user->createToken('api-token')->plainTextToken;

    return response()->json(['token' => $token]);
});

Step 7. Protect Routes

Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
    return $request->user();
});

Conclusion: You have successfully implemented authentication in Laravel 12 using Breeze for frontend authentication and Sanctum for API security. This setup is widely used in real-world applications.
