It wasn't any plan for layers of secutity which surprised me but the desire to add to the existing username/password login scheme with extra (unspecified) questions. It seems there is nothing to be gained from this approach. Furthermore, the OP specified > ...whenever someone opens their computer and I took "opens" to mean "switches on", which might mean having to look at what existing DMs have in the way of this functionality and of running another program. I believe lightdm can run scripts at login time. And, of course, there is always the opportunity to have an extra question via a GRUB password. (I hope this response raises my score above the recently awarded 0/10). -- Brian.
