A team of Dutch and Italian researchers has found that the
way you move your phone to your ear while answering a call is as distinct as a
fingerprint. You take it up at a speed and angle that’s almost impossible for
others to replicate. Which makes it more reliable password than anything you’d
come up with yourself. Down the line, simple movements like the way you shift
in your chair, might also replace passwords on your computer. It could also be
the master key to the seven million passwords you set up all over the Internet
but keep forgetting.
