It is designed from low level specifications implementations to high level frameworks integrations, to meet the needs of everyone. We'll be looking at authenticating a FastAPI app with Bearer (or Token-based) authentication, which involves generating security tokens called bearer tokens. In this tutorial we will learn how to add database backed user authentication to our FastAPI application. OAuth2PasswordBearer makes FastAPI know that it is a security scheme.
