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

This is a more or less advanced section. If you are just starting, you can skip it.

You don't necessarily need OAuth2 scopes, and you can handle authentication and authorization however you want.
