Let’s see it in detail

One of the key features of Sanctum is its ability to authenticate multiple devices for a single user. This means that a user can be logged in on multiple devices simultaneously, and each device will have its own unique access token. This is particularly useful for applications where the user may need to switch between devices, such as a mobile application and a web application.

In addition to supporting multiple devices, Sanctum also makes it easy to authenticate external services and APIs. This is useful for applications that need to authenticate third-party services, such as a backend service or an external API.

To use Sanctum, you’ll need to install the Laravel framework on your server and configure your application to use the Sanctum package. This process is relatively straightforward, and the Laravel documentation provides detailed instructions on how to set up Sanctum for your application.

#You may install Laravel Sanctum via the Composer package manager:
composer require laravel/sanctum

#publish the Sanctum configuration and migration files
php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"

#Run Migration
php artisan migrate

Once you have Sanctum installed and configured, you’ll need to create routes and controllers for your authentication flows. This will typically involve creating routes for logging in, logging out, and retrieving the authenticated user’s information. You can also use Sanctum to handle password resets and other authentication-related tasks.

One of the benefits of using Sanctum is its integration with Laravel’s built-in authentication system. This means that you can use Sanctum to handle your application’s authentication flows, while still taking advantage of Laravel’s built-in features, such as user roles and permissions.

Overall, Laravel Sanctum is a powerful and easy-to-use tool for building modern, secure, and scalable authentication systems. Whether you’re building a single-page application, a mobile application, or a traditional web application, Sanctum is an excellent choice for managing your application’s authentication flows.
