## Le flux `password` { #the-password-flow }

Revenons un peu en arrière et comprenons de quoi il s'agit.

Le « flux » `password` est l'une des manières (« flows ») définies dans OAuth2 pour gérer la sécurité et l'authentification.

Puedes usar `async def` o `def` normal.

Y puedes declarar dependencias con `async def` dentro de *path operation functions* normales `def`, o dependencias `def` dentro de *path operation functions* `async def`, etc.

No importa. **FastAPI** sabrá qué hacer.

    Снова, вы можете комбинировать `dataclasses` со стандартными аннотациями типов.

8. Обратите внимание, что эта *функция-обработчик пути* использует обычный `def` вместо `async def`.

    Как и всегда в FastAPI, вы можете сочетать `def` и `async def` по необходимости.

    Если хотите освежить в памяти, когда что использовать, посмотрите раздел _"Нет времени?"_ в документации про [`async` и `await`](../async.md#in-a-hurry).
