# 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

## Die `scopes` verwenden

Der Parameter `security_scopes` wird vom Typ `SecurityScopes` sein.

Dieses verfügt über ein Attribut `scopes` mit einer Liste, die alle von ihm selbst benötigten Scopes enthält und ferner alle Abhängigkeiten, die dieses als Unterabhängigkeit verwenden. Sprich, alle „Dependanten“ ... das mag verwirrend klingen, wird aber später noch einmal erklärt.

   * whose keys and values are the result of applying the provided mapping functions to the input

   * <p>For streams with defined encounter order (as defined in the Ordering section of the {@link
