# 패스워드 해싱을 이용한 OAuth2, JWT 토큰을 사용하는 Bearer 인증

모든 보안 흐름을 구성했으므로, 이제 <abbr title="JSON Web Tokens">JWT</abbr> 토큰과 패스워드 해싱을 사용해 애플리케이션을 안전하게 만들 것입니다.

이 코드는 실제로 애플리케이션에서 패스워드를 해싱하여 DB에 저장하는 등의 작업에 활용할 수 있습니다.

이전 장에 이어서 시작해 봅시다.

## JWT

JWT 는 "JSON Web Tokens" 을 의미합니다.

JSON 객체를 공백이 없는 긴 문자열로 인코딩하는 표준이며, 다음과 같은 형태입니다:

```

expose metrics without authentication, you don't need to use `mc` to generate prometheus config. You can skip reading further and move to 3.2 section.

The Prometheus endpoint in MinIO requires authentication by default. Prometheus supports a bearer token approach to authenticate prometheus scrape requests, override the default Prometheus config with the one generated using mc. To generate a Prometheus config for an alias, use [mc](https://docs.min.io/community/minio-object-store/reference/m...
