Laravel Sanctum makes authentication easy for web, mobile, and single-page apps. It's perfect for modern SPAs, mobile apps, or traditional websites. Sanctum simplifies user login, API access, and session management.

Modern apps need secure authentication without extra complexity. Laravel Sanctum offers a simple solution. It eliminates the need to manage tokens, routes, and middleware manually. It works well with Laravel, saving time while keeping security high.

Learn how Laravel Sanctum improves your authentication workflows. This guide will cover its main features, setup, and best practices. It's designed to help you create reliable, scalable authentication systems for any project.

What is Laravel Sanctum and Why Use It

Laravel Sanctum is a simple way to keep web and mobile apps safe. It makes token-based authentication easy, without the hassle of OAuth. It's great for SPAs and mobile apps, helping manage user sessions and API access.

The Evolution of Laravel Authentication

Laravel started with basic login systems. Then, Passport came for OAuth2 APIs. But, many apps don't need all that. Sanctum fills the gap with key features like API tokens and cookie handling for SPAs.

Key Features of Laravel Sanctum

• API Tokens: Secure tokens for user permissions, no need for passwords.
• SPA Support: Authenticates via cookies, no redirects, better user experience.
• Mobile Integration: Easy token-based auth for mobile apps, thanks to Sanctum's guides.

When to Choose Sanctum Over Passport

Choose Sanctum for token-based access in APIs or SPAs without OAuth2 needs. It's faster to set up than Passport, saving time. It's ideal for apps needing simple, secure authentication.

Getting Started with Laravel Sanctum: Prerequisites

Before starting with laravel sanctum setup, make sure your setup is ready. Laravel Sanctum works best with Laravel 7.x or higher and PHP 7.3+. These versions ensure compatibility with Sanctum’s features and security updates.

• Laravel Version: Check if your project uses Laravel 7 or newer with composer show laravel/framework.
• PHP Requirements: Use php -v to verify PHP 7.3+ is installed.
• Database Setup: Make sure your database connection is set in .env and migrations are current.

If starting from scratch, create a new Laravel project with: composer create-project --prefer-dist laravel/laravel your-project-name. If you have an existing app, update dependencies first.

A working authentication system is crucial. Sanctum uses Laravel’s default auth scaffolding. Run php artisan make:auth if you haven’t set up routes and views. Knowing about JSON Web Tokens (JWT) helps understand how Sanctum handles API tokens. But don’t worry, the documentation will guide you step by step.

Make sure these basics are covered before moving to laravel sanctum implementation. A solid foundation makes integration smoother. Ready? Let’s proceed to installation in the next section!

Installing Laravel Sanctum in Your Project

Starting your laravel sanctum integration journey is easy. This laravel sanctum tutorial will show you how to add Sanctum to your Laravel app. We'll make sure each step is clear and easy to follow.

First, open your terminal and run the Composer command to install Sanctum. Use:

composer require laravel/sanctum

This command adds Sanctum to your composer.json and gets the needed dependencies. Laravel then registers Sanctum’s service provider. This sets up the base for authentication features.

Running the Installation Command

After installing, run:

php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"

This command publishes Sanctum’s core files. You can now edit them. You won't need to do any manual setup unless you want to change settings later.

Publishing the Configuration File

Next, generate Sanctum’s configuration file by running:

php artisan vendor:publish --tag=sanctum-config

This creates a sanctum.php

file in

. You can adjust CORS policies and authentication guards here. This lets you tailor your app’s settings.

Setting Up the Database Migration

Run the migration command to create Sanctum’s tables:

php artisan migrate

This command creates important tables like personal_access_tokens. These tables store authentication data. You can only modify these migrations if you need custom columns or constraints.

With these steps, your app is now ready to use Sanctum’s authentication. Keep this guide close as we dive into configuration and implementation next!

Laravel Sanctum Authentication: Configuration Essentials

Getting good at laravel sanctum authentication starts with setting it up right. First, tweak the sanctum.php config file. Here are the main settings to adjust:

• Stateful Domains: List allowed domains in stateful array. Example: ['http://localhost:3000', 'https://api.yourapp.com']
• Token Expiration: Set expiration value (minutes). Default 43200 (28.8 hours)
• Guard Configuration: Define which guards Sanctum uses for laravel authentication checks

Update your .env file with:

• SANCTUM_STATEFUL_DOMAINS=localhost:3000
• SESSION_DOMAIN=yourdomain.com (for multi-domain setups)

For single-page apps, tweak CORS in cors.php:

'paths' => ['api/*', 'sanctum/csrf-cookie'],

Enable credentials with supports_credentials: true

Middleware like HandleStatefulRequests helps manage API requests. Use php artisan route:list to check middleware. Always test token expiration with Postman or browser tools.

Remember, wrong CORS settings lead to 419 errors. Check Laravel's official docs for environment-specific tweaks. Small adjustments here make laravel sanctum authentication secure for SPAs and APIs.

Implementing API Token Authentication

API tokens are key to secure user access in Laravel Sanctum. This guide covers how to create, manage, and protect laravel sanctum tokens. It also focuses on maintaining strong laravel sanctum security. Follow these steps to set up a token-based system for your app.

Creating and Issuing Tokens

Begin by giving tokens to users when they register or log in. Laravel makes it easy to generate tokens with just a few lines of code:

Keep the token safe on the client side for future use. Always check tokens on each API call to make sure they're real.

Token Abilities and Permissions

Use Sanctum's ability system to set up detailed permissions. When creating tokens, assign specific actions like ['read-posts', 'update-profile']:

• Use createToken('Token Name', ['scope1', 'scope2']) to limit access.
• Check permissions with hasTokenAbility('scope') in controller methods.

Limiting abilities helps if a token is leaked, making your laravel sanctum security better.

Revoking and Refreshing Tokens

Managing token lifecycles is crucial. Revoke tokens right after a user logs out:

Refresh tokens to give new ones without needing to log in again. Create a refresh endpoint to get a new token after checking the old one. Change tokens often to lower the risk of unauthorized access.

"Token revocation and rotation are essential for minimizing exposure after potential breaches." — Laravel Sanctum Documentation

Always store tokens in encrypted HTTP-only cookies for SPAs and mobile apps. This keeps them safe from client-side threats. Use these steps with rate limiting and CORS policies for even more security.

SPA Authentication with Laravel Sanctum

Laravel Sanctum makes Single Page Application (SPA) authentication easy with cookie-based sessions. It's better than token-based systems because it automatically handles secure cookies. This is great for Vue.js or React apps. First, set up routes for laravel sanctum login and logout.

• Define routes in web.php for authentication flows.
• Use Sanctum’s built-in guards to verify user sessions.
• Send cookies securely via HTTPS to protect user sessions.

For the laravel sanctum login process, create a login route. It should authenticate users and return a session cookie:

Example PHP route:

Route::post('/login', function (Request $request) { // Validate credentials Auth::attempt($request->only('email', 'password')) ? return 'Logged in' : abort(401); })->middleware('guest');

On the frontend, send login requests with JavaScript:

Vue.js example:

axios.post('/login', { email, password }) .then(response => { // Redirect to dashboard });

Sanctum automatically protects against CSRF when headers are set. Include X-XSRF-TOKEN in AJAX requests. This keeps security high without needing to manage tokens manually.

Use Sanctum’s middleware to protect routes. This ensures only logged-in users can access resources. Test it by logging in and seeing if the session stays active across page loads.

Mobile App Authentication Strategies

Mobile apps need secure but easy-to-use login methods. Laravel Sanctum makes this easier by using tokens for mobile apps. We'll look at how to set this up for iOS, Android, or Flutter apps.

Token-Based Authentication for Mobile Clients

Laravel Sanctum for mobile starts with creating secure API tokens. Use createToken() to make tokens linked to user accounts. For example:

Keep tokens safe using iOS’s Keychain or Android’s Keystore. Never put tokens in the app code.

• Android: Use Retrofit to send tokens in API calls.
• iOS: Use Alamofire for token storage and refresh.

Handling Authentication Headers

Every request from mobile apps must have the Sanctum Bearer token in headers. Here's how to do it:

1. Add Authorization: Bearer {token} to HTTP requests.
2. Test endpoints with tools like Postman to check header validation.

Remember, Sanctum uses these headers to check each API call.

Maintaining Persistent Sessions

Keep users logged in with automatic token refresh. Schedule checks to:

• Revoke expired tokens using revokeTokens().
• Get new tokens before they expire using Sanctum’s API.

Save refreshed tokens in secure, encrypted storage to prevent unauthorized access.

Securing Your Authentication with Best Practices

Strong laravel sanctum security is more than just setting it up. It's about turning good code into secure code. Let's look at three steps to make your app more secure without making things too complicated.

“Security is a shared responsibility—Laravel Sanctum provides tools, but implementation details matter most.”

Rate Limiting and Throttling

Stop brute-force attacks by limiting login and API requests. Laravel Sanctum works well with Laravel's throttling middleware. Add throttle:60,1 to routes to limit 60 requests per minute.

For sensitive areas like password resets, use throttle:5,1 to block fast retries.

CORS Configuration for Sanctum

Cross-Origin Resource Sharing (CORS) mistakes can let unauthorized access in. Set up CORS in config/cors.php to only allow trusted domains. Use:

• Allowed Origins: Whitelist frontend domains (e.g., https://yourapp.com).
• Credentials: Enable supports_credentials = true for secure token sending.

In production, turn off wildcard origins to stop unauthorized cross-domain requests.

Environment-specific Security Settings

Adjust security for each environment with .env variables:

1. Set SANCTUM_STATEFUL_DOMAINS to match current domains in staging/production.
2. Lower API_TOKEN_LIFETIME from 30 days to 7 days in production.
3. Turn off APP_DEBUG in live environments to hide system errors from users.

These settings help developers in testing while keeping live systems safe.

Troubleshooting Common Laravel Sanctum Issues

Even with a solid laravel sanctum setup, unexpected issues can arise. Let’s tackle the most frequent hurdles developers face and how to resolve them quickly.

• Authentication failures during laravel sanctum login: Check if middleware like auth:sanctum is correctly applied to routes. Missing headers like Accept: application/json can block token validation.
• CORS errors: Whitelist domains in config/cors.php. Ensure Sanctum::stateful() includes your frontend domains to avoid cross-origin blocks.
• Token persistence issues: Confirm sessions are stored properly. Tokens might not persist if session drivers like file aren’t configured for your environment.
• Configuration conflicts: Verify sanctum.php routes are registered via php artisan vendor:publish and routes are correctly imported.

A quick validation checklist:

1. Run php artisan route:list to confirm Sanctum routes are registered.
2. Test tokens via Auth::guard('sanctum')->user() in controllers.
3. Check .env variables for correct API domain listings.

“Sanctum issues often stem from overlooked configuration details—not code errors,” says Laravel community lead Taylor Otwell. “Methodical checks save time.”

For persistent errors, enable debug mode with APP_DEBUG=true to inspect raw server responses. Review browser console logs for network failures during laravel sanctum login attempts. If tokens aren’t refreshing, check abilities in token creation and ensure personal_access_tokens migration exists.

Remember: Sanctum integrates tightly with Laravel’s core. Most fixes involve cross-verifying middleware, CORS policies, and session storage settings. Take it step by step, and you’ll resolve even the trickiest issues.
