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.

But OAuth2 with scopes can be nicely integrated into your API (with OpenAPI) and your API docs.
