`パスワード`の「フロー」は、OAuth2で定義されているセキュリティと認証を扱う方法 (「フロー」) の1つです。

OAuth2は、バックエンドやAPIがユーザーを認証するサーバーから独立したものとして設計されていました。

しかし、この場合、同じ**FastAPI**アプリケーションがAPIと認証を処理します。

そこで、簡略化した箇所から見直してみましょう:

* ユーザーはフロントエンドで`ユーザー名`と`パスワード`を入力し、`Enter`を押します。
* フロントエンド (ユーザーのブラウザで実行中) は、`ユーザー名`と`パスワード`をAPIの特定のURL (`tokenUrl="token"`で宣言された) に送信します。
* APIは`ユーザー名`と`パスワード`をチェックし、「トークン」を返却します (まだ実装していません)。
    * 「トークン」はただの文字列であり、あとでこのユーザーを検証するために使用します。
