These Are The Most Common Lockscreen PINs

iPhone developer Daniel Amitay anonymously recorded and analysed passcodes of users of his Big Brother Camera Security iPhone app, resulting in an interesting list of the 10 most common passcodes, which, in order of popularity, include 1234, 0000, 2580, 1111, 5555, 5683 (spells LOVE), 0852, 2222, 1212, 1998.

Formulaic passwords are never a good idea, yet 15% of all passcode sets were represented by only 10 different passcodes (out of a possible 10,000). The implication? A thief (or just a prankster) could safely try 10 different passcodes on your iPhone without initiating the data wipe. With a 15% success rate, about 1 in 7 iPhones would easily unlock—even more if the intruder knows the users' years of birth, relationship status, etc.

    I'm glad you explained 5683. I was looking at my keyboard numpad trying to work out why that was so popular before reading down the page!

    Haha. oh dear... (goes to change passcode)

    With the raw data he has there, you could quite easily knock up a script that'll list the most likely passwords if you provide a known digit. While seeing somebody input their whole pin isn't that easy, just knowing the first or last digits would increase your odds dramatically.


      There's always a smart mouth who can't be civil isn't there? It's about time this sort of thing stopped.

      I think you'll find this kind of mentality is shared among the majority of users of any platform. Except maybe slackware users... maybe.

      Considering you can set up alphanumeric passwords instead of 4-digit passcodes on the iPhone...I say kindly to 'mark'


    When apple'anonymously' collected our whereabouts the world goes mad. When a guy 'anonymously' collects our passwords we thank him. Go figure.

      Yeah, I was expecting the comments to be full of people going crazy about this guy recording passcodes, but only one person mentions it..


      That had me stumped for a moment too, until you think about how many 13 year olds want or have an iPhone. Not to mention how many of them would find an application like this useful (Students always forget and leave phones lying around)
