    ## Usage

    Create an instance object and use that object as the dependency in `Depends()`.

    The dependency result will be a string containing the key value.

Every time you "log in with" Facebook, Google, GitHub, Microsoft, X (Twitter), that application is using OAuth2 with scopes.

In this section you will see how to manage authentication and authorization with the same OAuth2 with scopes in your **FastAPI** application.
