Except that a regular pin pad lets anyone enter the pin. Your pin code can only be keyed in by 1:1000000 people [citation needed]. So no, your pin is not on your forehead.

The best that they can do is use your actual face, within a few feet from you, while you're staring directly at the phone in their hands.
