I think Samsung does it with facial recognition on the Galaxy S's lock screen. Should work better and better and you don't need an additional sensor.

EDIT: So does Kinect for Xbox one.

As far as facial recognition on Kinect, I don't mind it as the keeper to my gaming system, but simply having my face unlock my bank account suffers the same problem as a finger print. Your face is on so many cameras every single day. A password should be kept private. Additionally, I'm a bald man with glasses, how many others with this description would be able to open my Xbox with their face? It is useful in combination with a password, but should not (and I would argue cannot) replace a password system of some kind.

OP mentioned using biometrics as a username in combination with a password. [1] seems to imply you can add a password or pass code.

That sounds still like crap. Has anyone defeated that already with still picture?

Yes it has: https://www.youtube.com/watch?v=NpNCXxtOzAo and http://www.ibtimes.co.uk/samsung-galaxy-s3-face-unlock-flaw-...

OP mentioned using biometrics as a username in combination with a password. [1] seems to imply you can add a password or pass code on xbox and I think you can do that too on a Galaxy S (?)
