* Configure quaisquer permissões e funções necessárias usando dependências.
* Nunca armazene senhas em texto simples, apenas hashes de senha.
* Implemente e use ferramentas criptográficas bem conhecidas, como tokens JWT e Passlib, etc.

Pero eso solo permitirá ciertos tipos de comunicación, excluyendo todo lo que implique credenciales: Cookies, headers de autorización como los utilizados con Bearer Tokens, etc.

Así que, para que todo funcione correctamente, es mejor especificar explícitamente los orígenes permitidos.

## Usa `CORSMiddleware`

Puedes configurarlo en tu aplicación **FastAPI** usando el `CORSMiddleware`.

* Configure any required permissions and roles using dependencies.
* Never store plaintext passwords, only password hashes.
* Implement and use well-known cryptographic tools, like Passlib and JWT tokens, etc.
* Add more granular permission controls with OAuth2 scopes where needed.
* ...etc.

Этот код можно реально использовать в своем приложении, сохранять хэши паролей в базе данных и т.д.

Мы продолжим разбираться, начиная с того места, на котором остановились в предыдущей главе.

## Про JWT

JWT означает "JSON Web Tokens".
