Laravel Passport is an OAuth 2.0 server implementation that simplifies API authentication in Laravel applications by enabling secure access to APIs through token-based authentication. To integrate it with social authentication providers, you need to use Laravel Socialite, which handles user authentication through social platforms such as Facebook, Google, and Discord. The integration combines the security of Passport's token-based authentication with the convenience of Socialite's social login features. To start, you'll scaffold a basic Laravel project, install the necessary packages, including Laravel Passport and Socialite, and configure the installed packages to work together seamlessly. You'll then modify the authentication flow by creating a controller that handles user login through social providers, adds routes for redirection and callback management, creates a React frontend with a social login component, and enables CORS configuration for communication between the frontend and backend. Finally, you can test the application, which should allow users to log in using their preferred social platforms while maintaining strict security standards. This integration simplifies user authentication while providing OAuth2-compliant token-based authentication, making it an important technique for securing modern web applications.
