		* Mas precisa de autenticação para aquele endpoint em específico.
		* Então, para autenticar com nossa API, ele manda um header de `Autorização` com o valor `Bearer` mais o token.
		* Se o token contém `foobar`, o conteúdo do header de `Autorização` será: `Bearer foobar`.

## **FastAPI**'s `OAuth2PasswordBearer`

**FastAPI** fornece várias ferramentas, em diferentes níveis de abstração, para implementar esses recursos de segurança.

/// info

The additional header `WWW-Authenticate` with value `Bearer` we are returning here is also part of the spec.

Any HTTP (error) status code 401 "UNAUTHORIZED" is supposed to also return a `WWW-Authenticate` header.

In the case of bearer tokens (our case), the value of that header should be `Bearer`.

You can actually skip that extra header and it would still work.

    * Pero necesita autenticación para ese endpoint específico.
    * Así que, para autenticarse con nuestra API, envía un `header` `Authorization` con un valor de `Bearer ` más el token.
    * Si el token contiene `foobar`, el contenido del `header` `Authorization` sería: `Bearer foobar`.

## `OAuth2PasswordBearer` de **FastAPI**

    * But it needs authentication for that specific endpoint.
    * So, to authenticate with our API, it sends a header `Authorization` with a value of `Bearer ` plus the token.
    * If the token contains `foobar`, the content of the `Authorization` header would be: `Bearer foobar`.
