I guess you just need to sit in front of the computer, and indicate to it that you want to login, maybe by clicking a button. A continuously monitoring camera may capture a hand or a face signal and automatically initiate authentication.
corresponding to "Bad password, please retype" you'll get
"Bad Face, make another one"
or after a few tries maybe
"Your face is too clean or too dirty, hair combed too well or it's too scrambled, wash your face, comb your hair again, adjust the light, face the camera, hold your head in the position and make the same expression as when you took the picture (I am the computer trying to help you)"
or after some more tries
"You look like a thief"
