class OAuth2PasswordRequestForm:
    """
    This is a dependency class to collect the `username` and `password` as form data
    for an OAuth2 password flow.

    The OAuth2 specification dictates that for a password flow the data should be
    collected using form data (instead of JSON) and that it should have the specific
    fields `username` and `password`.

!!! warning "Aviso"
    Você pode declarar vários parâmetros `File` e `Form` em uma *operação de caminho*, mas não é possível declarar campos `Body` para receber como JSON, pois a requisição terá o corpo codificado usando `multipart/form-data` ao invés de `application/json`.

    Isso não é uma limitação do **FastAPI** , é parte do protocolo HTTP.
