**FastAPI** bietet mehrere Tools auf unterschiedlichen Abstraktionsebenen zur Implementierung dieser Sicherheitsfunktionen.

In diesem Beispiel verwenden wir **OAuth2** mit dem **Password**-Flow und einem **Bearer**-Token. Wir machen das mit der Klasse `OAuth2PasswordBearer`.

/// info

Ein „Bearer“-Token ist nicht die einzige Option.

Aber es ist die beste für unseren Anwendungsfall.
