Let's imagine that you have your **backend** API in some domain.

And you have a **frontend** in another domain or in a different path of the same domain (or in a mobile application).

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

Bạn cũng có thể sử dụng nó để sinh code tự động, với các client giao viết qua API của bạn. Ví dụ, frontend, mobile hoặc các ứng dụng IoT.

## Tóm lại, từng bước một

### Bước 1: import `FastAPI`

```Python hl_lines="1"
{!../../../docs_src/first_steps/tutorial001.py!}
```

Ebenfalls können Sie es verwenden, um automatisch Code für Clients zu generieren, die mit Ihrer API kommunizieren. Zum Beispiel für Frontend-, Mobile- oder IoT-Anwendungen.
