According to Datagenetics 10.71% of 4 digit passcodes are 1234. Data Genetics did some number crunching on ATM pin data, not sure how they got it but it sounds legal. That doesn’t necessarily translate into a 10% chance of it working on your phone since this was from ATM cards, but it might be close. Together these top ten pins represent 23.34% of all pin numbers. So go ahead and amaze your friends at a party and guess their pins. Interestingly, the least used pin was 8068.
