Laravel Sanctum vs Passport: Choosing the Right Authentication Tool

Laravel, one of the most popular PHP frameworks, provides robust tools for handling authentication and API security. Two of the most widely used packages for this purpose are Sanctum and Passport. While both serve the purpose of securing your application, they cater to different use cases. In this blog, we’ll dive deep into what Sanctum and Passport are, how they differ, and when to use each of them.

What is Laravel Sanctum?

Laravel Sanctum is a lightweight package designed for token-based authentication in single-page applications (SPAs), mobile applications, and simple API token authentication. It provides a simple way to authenticate users and issue API tokens without the complexity of OAuth.

Key Features of Sanctum:

1. API Token Authentication: Sanctum allows users to generate API tokens that can be used to authenticate requests.
2. SPA Authentication: It provides a seamless way to authenticate SPAs that interact with your Laravel backend.
3. Lightweight: Sanctum is minimalistic and doesn’t include the overhead of OAuth.
4. Session-Based Authentication: For SPAs, Sanctum can use Laravel’s session-based authentication, making it easy to integrate with existing applications.

When to Use Sanctum?

• You’re building a single-page application (SPA) that interacts with a Laravel backend.
• You need simple API token authentication for mobile apps or third-party services.
• You want a lightweight solution without the complexity of OAuth.

What is a Laravel Passport?

Laravel Passport is a full-featured OAuth2 server implementation for Laravel. It allows you to issue access tokens and manage OAuth2 authentication for your application. Passport is ideal for applications that need to implement OAuth2 standards for third-party authentication.

Key Features of Passport:

1. OAuth2 Server: Passport provides a complete OAuth2 server implementation.
2. Access Tokens: It supports issuing access tokens, refresh tokens, and personal access tokens.
3. Third-Party Authentication: Passport is perfect for applications that need to allow third-party services to authenticate users.
4. Scalability: Passport is designed for applications that require robust and scalable authentication mechanisms.

When to Use Passport?

• You’re building an API-driven application that needs OAuth2 authentication.
• You want to allow third-party applications to authenticate with your API.
• You need advanced features like token scopes, refresh tokens, and token revocation.

Sanctum vs. Passport: Key Differences

How to Set Up Sanctum in Laravel

Step 1: Install Sanctum

Run the following command to install Sanctum:

composer require laravel/sanctum

Step 2: Publish Sanctum Configuration

Publish the configuration file using:

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

Step 3: Run Migrations

Sanctum requires a database table to store API tokens. Run the migration:

php artisan migrate

Step 4: Add Middleware

Add the EnsureFrontendRequestsAreStateful middleware to your app/Http/Kernel.php file if you’re using Sanctum for SPAs.

Step 5: Issue API Tokens

You can issue tokens to users like this:

$user = User::find(1);

$token = $user->createToken('token-name')->plainTextToken;

How to Set Up Passport in Laravel

Step 1: Install Passport

Install Passport via Composer:

composer require laravel/passport

Step 2: Run Migrations

Passport requires several database tables. Run the migration:

php artisan migrate

Step 3: Install Passport

Install Passport using the passport:install command:

php artisan passport:install

This command generates encryption keys and creates client credentials.

Step 4: Configure API Authentication

Update the auth.php configuration file to use Passport for API authentication:

'api' => [

    'driver' => 'passport',

    'provider' => 'users',

],

Step 5: Issue Access Tokens

You can issue tokens using Passport’s built-in methods:

$user = User::find(1);

$token = $user->createToken('token-name')->accessToken;

Choosing Between Sanctum and Passport

• Use Sanctum if:
• You’re building a simple SPA or mobile app.
• You don’t need OAuth2 functionality.
• You want a lightweight and easy-to-implement solution.
• Use Passport if:
• You’re building an API that third-party applications will consume.
• You need OAuth2 compliance.
• You require advanced features like token scopes and refresh tokens.

Conclusion

Both Laravel Sanctum and Passport are powerful tools for handling authentication in Laravel applications. Sanctum is perfect for lightweight, token-based authentication, while Passport is ideal for full OAuth2 implementations. By understanding their differences and use cases, you can choose the right tool for your project and ensure your application is secure and scalable.

Whether you’re building a simple SPA or a complex API-driven application, Laravel has you covered with Sanctum and Passport. Happy coding!
