Tech consultancy company DataGenetics has analyzed the popularity of numeric passwords. What they found confirms previous research that most of our four-digit PINs are way too predictable. DataGenetics analyzed nearly 3.4 million leaked four-digit passwords – such as those used for banking or to lock your phone – and figured out which are the most popular. These are PINs you should not use, because they’re incredibly predictable. A staggering 26.83% of all passwords could be guessed by attempting just 20 combinations! So out of the 10,000 possible combinations for four-digit codes, which is the most popular? Nearly 11% of the 3.4 million passwords were 1234. Other high frequency PINs are years and dates. Here are the most popular PINs:

Researchers also discovered other interesting patterns – people apparently prefer even numbers to odd ones, for instance. As for the least frequent PINs, 8068 was the rarest combination, used in just 0.000744% of the surveyed passwords. Of course, you don’t want to use that either now – as DataGenetics notes, “Hackers can read too!”
