We have just deployed a couple of Linux server. Each sysadmin will have his own account on the server (i.e.: jsmith), and will connect using SSH with a certificate which will be put into the "authorized_keys" file in their home directory. Once connected on the server, if they want to issue an elevated command, they will do like:

sudo ifconfig

They will then enter the root password.

What I would like to know now are the best practices in managing that root password. Should I change it periodicaly? And how do I share that new password with the sysadmins?

**Of course I will disable the root logon in SSH.
