+Docker Hub OIDC can also be used with `registry-auth`. Grant `id-token: write`,
+set `DOCKERHUB_OIDC_CONNECTIONID`, pass the Docker Hub organization name as
+`username`, and omit `password` for the Docker Hub object:
+
+```yaml

 ### Set scopes for the authentication token
 
 The `scope` input allows limiting registry credentials to a specific repository
