- The redirection URI (callback handler) receives the OAuth2 callback, verifies the state parameter, and obtains a Token.
- Using the id_token the callback handler further talks to Google OAuth2 Token URL to obtain an JWT id_token.
- Once obtained the JWT id_token is further sent to STS endpoint i.e MinIO to retrieve temporary credentials.
- Temporary credentials are displayed on the browser upon successful retrieval.

## Using MinIO Console

- `jwt:sub`
- `jwt:iss`
- `jwt:aud`
- `jwt:jti`
- `jwt:upn`
- `jwt:name`
- `jwt:groups`
- `jwt:given_name`
- `jwt:family_name`
- `jwt:middle_name`
- `jwt:nickname`
- `jwt:preferred_username`
- `jwt:profile`

### 2. Configure authentication type for Prometheus metrics

MinIO supports two authentication modes for Prometheus either `jwt` or `public`, by default MinIO runs in `jwt` mode. To allow public access without authentication for prometheus metrics set environment as follows.

```
export MINIO_PROMETHEUS_AUTH_TYPE="public"
minio server ~/test
```
