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

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

/// info | "informação"



///

	Um token "bearer" não é a única opção.

	Mas é a melhor no nosso caso.

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.

## Usar `CORSMiddleware`

Você pode configurá-lo em sua aplicação **FastAPI** usando o `CORSMiddleware`.

* Importe `CORSMiddleware`.
* Crie uma lista de origens permitidas (como strings).
* Adicione-a como um "middleware" à sua aplicação **FastAPI**.
