Ein Beispiel könnte sein, dass Sie einen externen Authentifizierungsanbieter haben, mit dem Sie sich verbinden müssen.

Sie senden ihm ein Token und er gibt einen authentifizierten Benutzer zurück.

For example, you can configure STS with Client Grants (KeyCloak) using the guides at [MinIO STS Quickstart Guide](https://docs.min.io/community/minio-object-store/developers/security-token-service.html) and [KeyCloak Configuration Guide](https://github.com/minio/minio/blob/master/docs/sts/keycloak.md). Once this is done, STS credentials can be generated:
