How can you get someone to tell you their password? Get a camera and a microphone, then just ask!
Most people don’t practice the 4 rules of good passwords (GOAL – Gibberish, Only you can know it, All the characters, Long). In fact most people practice the exact opposite of each of these 4 rules. Watch how trivial some people’s passwords really are, and watch how easy it is to get them to divulge.
Obviously the big rule violated here is Only you can know your password. If you were stopped on the street and asked what your password is, what do you think the proper response would be?
“I never divulge my password to anyone, but even if I did it would just look like a bunch of long gibberish to you.”
