socialite VS multi-tenant

Going deeper than just blade files, Laravel is a full MVC framework and so includes things like Models and Controllers out of the box that can be used to organize your server-rendered code. Authentication is also baked in by default, and with first-party packages like Breeze, Sanctum, or Socialite, you can include user registration, login, API-based authentication, social sign-ups, and role-based permissions with near zero configuration.

Have you considered https://github.com/laravel/socialite? Check https://socialiteproviders.com to see if the provider is supported already. If not, it's probably easier to write a custom provider than it is to write everything from scratch without Socialite.

Laravel Socialite enables you to handle OAuth authentication more seamlessly. This tool allows users to login via social networking sites such as Facebook, LinkedIn, Instagram, Twitter, Google, Bitbucket, etc. This is one of the popular Laravel features that is commonly used in most of the Laravel development.
