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.
