# Managing IAM authentication user

Available in VPC

Ncloud Kubernetes Service cluster supports two authentication methods for managing IAM authenticated users: ConfigMap and access entry. Clusters using ConfigMap method can be changed to the access entry method, but the reverse change is not supported.

              Caution

              

If you're switching from the ConfigMap to access entry method, the user added to the ConfigMap will not be maintained.
