We already know people are really bad at picking passwords, but they’re also god awful at choosing obvious, crackable credit card PINs. In fact, the most common four-digit code is not-so shockingly, 1-2-3-4. Come on, people.
Privacy guru Nick Berry crunched the numbers from previously exposed pass codes to find the 20 most popular and 20 rarest PINs. Collective facepalm! He learned that 1-2-3-4 is used more than 10 per cent of the time. And it doesn’t get better as the list goes on — the second most common PIN is 1-1-1-1. The third? 0-0-0-0. Honestly, as it continues, it gets even more depressing, because most of the combinations are just single digits repeated four times. God forbid you get hacked, but if you use one of these PINs, you’re asking for it.
Sadly enough, Berry found that his list of most common combos can be used to guess more than a quarter of PINs out there. You can see the list above, but please, if yours is mentioned, go change it. Right now! [Data Genetics via Apartment Therapy]

Wonder why 1004 is so popular? Cb radio users? Also by publishing the most and least common lists isn’t there a danger they will swap places?
No
Also, I wonder why 6969 is so popular?
…oh
I doubt it as most of the people that would look at the list wouldn’t have a silly PIN.
This list is likely to be published everywhere, as everyone has at least one pin, it’s a general interest story.
From article: “Many people also asked the significance of 1004 in the four character PIN table. This comes from Korean speakers. When spoken, “1004″ is cheonsa (cheon = 1000, sa=4).
“Cheonsa” also happens to be the Korean word for Angel.”
Thank you.
Yeah, I’ve done this. If I intend to secure something that isn’t remotely sensitive, I might just pick a password that’s really easy to remember. Perhaps many people are doing the same.
The author doesn’t state the kind of databases these numbers come from. I’d really hope it isn’t credit cards – perhaps it’s just private teleconference systems.
The frequency of 19XX numbers was also quite disturbing.
my pin number of 7581 is safe then
Ha. They’ll never guess my Umpteen and Twelvty three pin number.
The source link was a really interesting read for those who want to know more about the data.
0001 stupid stupid stupid password!
