    사용해야 한다면 `OAuth2PasswordRequestForm` 대신 `OAuth2PasswordRequestFormStrict`를 사용하면 됩니다.

* `client_id`(선택적으로 사용) (예제에서는 필요하지 않습니다).
* `client_secret`(선택적으로 사용) (예제에서는 필요하지 않습니다).

!!! 정보
    `OAuth2PasswordRequestForm`은 `OAuth2PasswordBearer`와 같이 **FastAPI**에 대한 특수 클래스가 아닙니다.

    `OAuth2PasswordBearer`는 **FastAPI**가 보안 체계임을 알도록 합니다. 그래서 OpenAPI에 그렇게 추가됩니다.

    Wenn Sie es erzwingen müssen, verwenden Sie `OAuth2PasswordRequestFormStrict` anstelle von `OAuth2PasswordRequestForm`.

* Eine optionale `client_id` (benötigen wir für unser Beispiel nicht).
* Ein optionales `client_secret` (benötigen wir für unser Beispiel nicht).

!!! info
    `OAuth2PasswordRequestForm` ist keine spezielle Klasse für **FastAPI**, so wie `OAuth2PasswordBearer`.

    If you need to enforce it, use `OAuth2PasswordRequestFormStrict` instead of `OAuth2PasswordRequestForm`.

* An optional `client_id` (we don't need it for our example).
* An optional `client_secret` (we don't need it for our example).

    The `OAuth2PasswordRequestForm` is not a special class for **FastAPI** as is `OAuth2PasswordBearer`.
