What is the default password for user ; "asterisk" for FreePBX

I needed to allow the redundant asterisk server to connect to the primary asterisk server so that a schedule can be created on the redundant server using backup/restore module but ran into issues; The asterisk user is requesting a password and I do not recall ever setting up one for it so,

Is there a default system set password for user asterisk

If I change the password will it affect the functioning of freePBX in any way? I want to be sure that that user is not being used by any function in the application itself to perform any tasks.

Thanks in advance

The ‘asterisk’ user doesn’t have a password by default, but, you should be using root to do your backups, not asterisk.
