You can automate password changes for Cisco local accounts and Cisco Enable passwords. You can also use Heartbeat on these accounts.
Create Secrets using these Secret Templates (either SSH or blank if you want Telnet).
You can see the commands that will be used for the Secret by going to the Remote Password Changing tab.
To see the commands for the Heartbeat, you will need to look at the Password Changer itself, under Administration | Remote Password Changing | Password Changers.
