## O `OAuth2PasswordBearer` do **FastAPI** { #fastapis-oauth2passwordbearer }

O **FastAPI** fornece várias ferramentas, em diferentes níveis de abstração, para implementar essas funcionalidades de segurança.

Neste exemplo, vamos usar **OAuth2**, com o fluxo **Password**, usando um token **Bearer**. Fazemos isso usando a classe `OAuth2PasswordBearer`.

You could also define it as a normal function instead of `async def`:

{* ../../docs_src/first_steps/tutorial003_py39.py hl[7] *}

/// note

If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

///

### Step 5: return the content { #step-5-return-the-content }

E o Swagger UI tem suportado esse campo `examples` particular há algum tempo. Então, você pode usá-lo para **mostrar** diferentes **exemplos na UI da documentação**.

O formato desse campo `examples` específico do OpenAPI é um `dict` com **vários exemplos** (em vez de uma `list`), cada um com informações extras que também serão adicionadas ao **OpenAPI**.
