change root password after cluster created

[dev03jr]

After creating the cluster and adding the 03 nodes, can I change the root password? What is the password I use to log into the cluster? Could there be a problem?

You could change root pw on each node individually, eg. in console window with cmd passwd.
When you pve logged in the gui you get access to the other cluster nodes with set-up'ed ssh-key which you already done when you definded cluster members together.

You can simply change with the "passwd" command on each individual node after logging in to root. There should not be any downside to this, clustered Proxmox nodes have an SSH key set up as part of the process.
