I’ll crack you by the sparkle in my eyes
Jan Krissler, the same biometric hacker who eloquently demonstrates the “vulnerability of the thumb” and who hacked from a photograph of the Minister of Defense of Germany , can recognize your password / PIN by the glint of his eyes.
As practice has shown, the eyes are not only a mirror of the soul, but also just a mirror, which means you can peek into it what is happening on your screen.
