After you’ve completed the procedure that required passwordless root SSH, you may disable it for all nodes.

  1. Log in as root on the queen.
  2. Issue the command to disable passwordless SSH, providing the IP address of each worker node in the instance: # ncli sshkeys disable -n <IP1,IP2,...>

    When specifying multiple node IP addresses using the -n option, they must be separated by a comma only, without spaces.

  3. Whenever you need to re-enable passwordless SSH (for example, when adding a node, upgrading, and so on) the procedure will direct you to do so.
