O `OAuth2PasswordRequestForm` não é uma classe especial para **FastAPI** como é `OAuth2PasswordBearer`.

`OAuth2PasswordBearer` faz com que **FastAPI** saiba que é um esquema de segurança. Portanto, é adicionado dessa forma ao OpenAPI.

Mas `OAuth2PasswordRequestForm` é apenas uma dependência de classe que você mesmo poderia ter escrito ou poderia ter declarado os parâmetros do `Form` (formulário) diretamente.

   * The primary feature of a RateLimiter is its "stable rate", the maximum rate that it should
   * allow in normal conditions. This is enforced by "throttling" incoming requests as needed. For
   * example, we could compute the appropriate throttle time for an incoming request, and make the
   * calling thread wait for that time.
