## Technische Details

Die Klasse `BackgroundTasks` stammt direkt von <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.

# Einfaches OAuth2 mit Password und Bearer

Lassen Sie uns nun auf dem vorherigen Kapitel aufbauen und die fehlenden Teile hinzufügen, um einen vollständigen Sicherheits-Flow zu erhalten.

## `username` und `password` entgegennehmen

Wir werden **FastAPIs** Sicherheits-Werkzeuge verwenden, um den `username` und das `password` entgegenzunehmen.
