Your Screen can be Seen from Far Away

Like the 2nd floor of a mall.

What about using using a real camera, instead of a phone?

HD video camera > zoom > record > play it back slowly > get password

The Defence

Back to the wall when entering passwords, and look up first, everyone forgets to look up.
