# OAuth2 com Senha (e hashing), Bearer com tokens JWT

Agora que temos todo o fluxo de segurança, vamos tornar a aplicação realmente segura, usando tokens <abbr title="JSON Web Tokens">JWT</abbr> e hashing de senhas seguras.

Este código é algo que você pode realmente usar na sua aplicação, salvar os hashes das senhas no seu banco de dados, etc.

Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## Sobre o JWT

        Thanks for your interest in FastAPI! 🚀

        Please follow these instructions, fill every question, and do every step. 🙏

        I'm asking this because answering questions and solving problems in GitHub is what consumes most of the time.

Here's how to help others with questions (in discussions or issues):

### Understand the question { #understand-the-question }

* Check if you can understand what is the **purpose** and use case of the person asking.

* Then check if the question (the vast majority are questions) is **clear**.

 * [IOException].
 *
 * Most callers won't need this interface, and should use [Response.trailers] instead.
 *
 * This interface is for test and production code that creates [Response] instances without making
 * an HTTP call to a remote server.
