The hierarchy is like:

* **Uvicorn**: an ASGI server

        * **FastAPI**: (uses Starlette) an API microframework with several additional features for building APIs, with data validation, etc.

Django REST framework was created to be a flexible toolkit for building Web APIs using Django underneath, to improve its API capabilities.

A "bearer" token is not the only option.

But it's the best one for our use case.

And it might be the best for most use cases, unless you are an OAuth2 expert and know exactly why there's another option that better suits your needs.

In that case, **FastAPI** also provides you with the tools to build it.
