I just got this new Dell laptop, system took my image as sign in. I have not set up PIN. Now I had a hair cut, it does not recognize my image and ask for PIN as credential. Need help.
are you talking about windows 10? There's always two options password and pin, if you have the right camera then there is also Windows Hello facial recognition.
Try 0000 or 1111, if you never set a pin. But I agree with barty, I cannot imagine windows would allow your only login credential to be facial recognition.
