Analysis of PIN Data
An analysis of 3.4 million four-digit PINs. ("1234" is the most common: 10.7% of all PINs. The top 20 PINs are 26.8% of the total. "8068" is the least common PIN -- that'll probably change now that the fact is published.)

There is no particular reason for 8093, some number has to be the least popular. If you look at the graphs in the data, they are pretty flat one you get out to the tail.
ie. most people pick obvious numbers or patterns on the keypad, then dates - once you get out to real random numbers their distribution is pretty random
