PIN/Password Analysis Shows That We’re Predictable

August 6th, 2013

Computer SecurityThe author of the linked article accumulated a database of hacked PINs and numeric passwords, then analyzed it to see what patterns emerged. Here are some of the highlights:

  • 20% of all PINs use just five different numbers: 1234, 1111, 0000, 1212, and 7777.
  • The fourth most popular seven-digit password is 8675309. (Wait for it…)
  • Using a year in the form 19XX is a bad idea.
  • The least used PIN is 8068.
  • Including 007, 420, and 69 may seem like a neat idea, but they turn out to be quite common.
  • Numbers made from drawing lines or patterns on the keypad are also popular.
