User Account And Password Requirements - HP StoreOnce 4900 Backup Installation And Configuration Manual

NOTE: Note that once the Admin account password has been changed, its password cannot
be changed back to admin as this password is not sufficiently complex. The only way to revert
that password back to admin is via the HPresetpassword account which is only available on
the local console of the device.
As you create new users, use the StoreOnce CLI system save config command to save
details of the new user accounts. This command does not save the password details, so
passwords for additional users should also be saved offline and kept in sync with the details
held on the HP StoreOnce Backup system.
