 If your application runs on a Kubernetes cluster, you can authenticate to MongoDB by using
 the {+driver-short+}'s built-in Kubernetes support.
 
-To specify Kubernetes OIDC as the authentication mechanism, set the following 
-options in your connection string:
+Select from the :guilabel:`Connection String` or :guilabel:`MongoCredential` tabs to
+see the corresponding syntax.
 
-- ``authMechanism``: Set to ``MONGODB-OIDC``.
-- ``authMechanismProperties``: Set to ``ENVIRONMENT:k8s``. 
+.. tabs::
 
-The following code example shows how to set the preceding connection options:
