Nick Berry, a data technology consultant running the website
Data Genetics,
analyzed data of 4 digit passwords and pin numbers to determine which combinations are the most and which the least used and generally to poke around for other patterns. Using tables of data containing ~3.7 million passwords that had been hacked or uncovered and released, he determined frequency of use. The most common is 1234, which about 10.7% of people use, followed by 1111 (~6%), 0000 (~1.9%), 1212 (~1.2%). The least popular (which surely has changed by disclosing it) was 8068 (~.00007%), though there were many other low use numbers. His article is full of statistical goodness and interesting observations, including some thoughts on how to maintain safe passwords. Via
