Наприклад, один зі способів використання специфікації OAuth2 (так званий "password flow") вимагає надсилати `username` та `password` як поля форми.

<abbr title="Специфікація">spec</abbr> вимагає, щоб ці поля мали точні назви `username` і `password` та надсилалися у вигляді полів форми, а не JSON.

## Pegue o `username` (nome de usuário) e `password` (senha)

É utilizado o utils de segurança da **FastAPI** para obter o `username` e a `password`.

OAuth2 especifica que ao usar o "password flow" (fluxo de senha), que estamos usando, o cliente/usuário deve enviar os campos `username` e `password` como dados do formulário.
