# Update configuration cluster server credentials

This function updates the username or remote access key for a cluster server.

Important:

 If you log in to a configuration cluster server that is not the parent server, nothing will indicate that the server is part of a configuration cluster. You can only* view and modify this information from the master server.

* We recommend that you run this function as a POST request with SSL enabled:
  * The length of the remote access key may cause problems if you run the function with the GET method (for example, a URL in your browser).
  * You risk security problems if you enter a remote access key through the GET method.
