The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication.

```

Refer [Prometheus documentation](https://prometheus.io/docs/introduction/first_steps/) for more details.

### 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

 * <tt>NtlmHttpFilter</tt> should be used/b>. For custom NTLM HTTP Authentication schemes the <tt>NtlmSsp</tt> may be used.

 * Read <a href="../../../ntlmhttpauth.html">jCIFS NTLM HTTP Authentication and the Network Explorer Servlet</a> related information.

Dex is an identity service that uses OpenID Connect to drive authentication for apps. Dex acts as a portal to other identity providers through "connectors." This lets dex defer authentication to LDAP servers, SAML providers, or established identity providers like GitHub, Google, and Active Directory. Clients write their authentication logic once to talk to dex, then dex handles the protocols for a given backend.
