But voice recognition while useful feels much more awkward to do instead of a gentle hand movement, that feels pretty high tech imo.

Password system requires you to input the password and someone might discover it.
Facial recognition, while just taking a little time to do, no one can fake or get through that security system. Unless you have a twin brother.
