What are you talking about?
Do you know how many forums, bank sites, email accounts make you create or creates a password for you? How are you even posting on here if you dont? Maybe you use 4 numbers but a lot of sites ask for 6 letters min with two numbers. That's a lot of passwords and sure you can make them all the same but people don't.
Maybe you have a photographic memory and your face changes every other day and your voice keeps crapping out on you but others arent like that. You are special so please think me a moron for being human and forgetting a password that I made 4 years ago.
Also don't presume to think that a moron like me doesn't know about password recovery.
Hey Issac Newton here's an idea. When setting up the facial recognition how about having some sort of safety feature like "mothers maiden name" "where was you born" and for super people like you a password as some sort of password recovery to reset the facial recovery software and grant you access when you completely change your face or lose your voice..
Not a bad idea from a moron hey? The facial recognition is just that, to recognise it's you and adjust to your settings. It doesn't have to be about security so a password might not even be needed.
I don't know what you mean about the avatars (I am a moron) but if it's something to do with mimicking the movement of the host face then that's something completely different. You're asking it to remember points on your face not sing and dance with you.
