The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment using the MinIO Console, an embedded
object browser built into MinIO Server. Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the
root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.

Dann können wir `secrets.compare_digest()` verwenden, um sicherzustellen, dass `credentials.username` `"stanleyjobson"` und `credentials.password` `"swordfish"` ist.

Dies wäre das gleiche wie:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Einen Error zurückgeben
    ...
```

**Note**: On distributed systems, root credentials are recommend to be defined by exporting the `MINIO_ROOT_USER` and  `MINIO_ROOT_PASSWORD` environment variables. If no value is set MinIO setup will assume `minioadmin/minioadmin` as default credentials. If a domain is required, it must be specified by defining and exporting the `MINIO_DOMAIN` environment variable.

This will open the login page of keycloak, upon successful login, STS credentials along with any buckets discovered using the credentials will be printed on the screen, for example:

```
