Por ejemplo, en una de las formas en las que se puede usar la especificación OAuth2 (llamada "password flow") se requiere enviar un `username` y `password` como campos de formulario.

int maxDepth = -1               // Max depth (-1 = unlimited)
long maxAccessCount = 0         // Max URLs (0 = unlimited)
```

## Obtener el `username` y `password` { #get-the-username-and-password }

Vamos a usar las utilidades de seguridad de **FastAPI** para obtener el `username` y `password`.

OAuth2 especifica que cuando se utiliza el "password flow" (que estamos usando), el cliente/usuario debe enviar campos `username` y `password` como form data.

Y la especificación dice que los campos deben llamarse así. Por lo que `user-name` o `email` no funcionarían.

    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

/// warning

The supporting additional functions `fake_password_hasher` and `fake_save_user` are just to demo a possible flow of the data, but they of course are not providing any real security.

Reducing code duplication is one of the core ideas in **FastAPI**.
