Is it possible to enter a password on the alarm control unit?

Yes, you can enter up to 19 passwords for a total of 20 different users: one of these is in fact named "Guest", which usually comes without the permission settings for the settings and configuration menus, and is automatically activated after a period of inactivity (approx. 2min) of the By-me control unit. The first user that is generated on installation of the system is the Administrator, which has full management of all users on the control unit, thus able to create them, decide access permissions, passwords, etc.
