#### Give full admin permissions

- admin:*

### 5. Using an external IDP for admin users

Admin users can also be externally managed by an IDP by configuring admin policy with
special permissions listed above. Follow [MinIO STS Quickstart Guide](https://min.io/docs/minio/linux/developers/security-token-service.html) to manage users with an IDP.
