あるドメインに、**バックエンド** APIを持っているとしましょう。

そして、別のドメインか同じドメインの違うパス（またはモバイルアプリケーションの中）に **フロントエンド**を持っています。

さらに、フロントエンドが**ユーザー名**と**パスワード**を使って、バックエンドで認証する方法を用意したいです。

**FastAPI**では、これを**OAuth2**を使用して構築できます。

ですが、ちょっとした必要な情報を探すために、長い仕様のすべてを読む必要はありません。

**FastAPI**が提供するツールを使って、セキュリティを制御してみましょう。

    The `--upgrade` option tells `pip` to upgrade the packages if they are already installed.

    Because the previous step copying the file could be detected by the **Docker cache**, this step will also **use the Docker cache** when available.
