Laravel API Authentication with Sanctum: Complete Production Guide (2026)
If you're building APIs with Laravel, authentication is one of the most critical parts of your system. In real-world applications—especially mobile apps and SaaS platforms—you need a secure, scalable, and simple authentication system.
Laravel Sanctum is the best lightweight solution for token-based authentication.
In this guide, you’ll learn how to implement Laravel Sanctum in a production-ready way, including best practices that many tutorials ignore.
🔐 Why Choose Sanctum Over Passport?
Sanctum is ideal when:
- You build SPA or mobile apps
- You need simple token authentication
- You don’t need full OAuth2
Advantages:
- Lightweight
- Easy to implement
- Secure token handling
⚙️ Step 1: Install and Configure Sanctum
composer require laravel/sanctum
php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"
php artisan migrate
Then update your User model:
use Laravel\Sanctum\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens;
}
🔑 Step 2: Create API Login Endpoint
public function login(Request $request)
{
$credentials = $request->only('email', 'password');
if (!Auth::attempt($credentials)) {
return response()->json(['message' => 'Invalid credentials'], 401);
}
$user = Auth::user();
$token = $user->createToken('mobile_token')->plainTextToken;
return response()->json([
'user' => $user,
'token' => $token
]);
}
📲 Step 3: Protect Routes with Middleware
In routes/api.php:
Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
return $request->user();
});
🧠 Advanced: Token Abilities (Scopes)
You can restrict tokens:
$token = $user->createToken('admin_token', ['admin']);
Check ability:
if ($request->user()->tokenCan('admin')) {
// allow action
}
🔥 Best Practices for Production
1. Use HTTPS Only
Never expose tokens over HTTP.
2. Store Tokens Securely
In mobile apps:
- Use secure storage (NOT localStorage)
3. Token Expiration Strategy
Sanctum doesn't expire tokens by default → implement manually.
4. Revoke Tokens on Logout
$request->user()->tokens()->delete();
📊 Real Use Case (Your Scenario)
For your Flutter app:
- Login → get token
- Store token securely
- Send token in headers
Authorization: Bearer {token}
