Well, if you don't mind using a complex password on a keyboard-less device, the whole discussion is moot. Aren't we talking about alternatives to conventional password entry because it is a great nuisance? Voice recognition, Face recognition and Finger Printing all seem reasonable alternatives. I do believe it is a matter of time before they become viable in smartphones. How about an RFID chip in your wrist watch which makes your smartphone log in. Outside of a meter or two, it will ask for a complex password. Why not? I will buy it :-)
