For those paranoid about both losing their phone and having your information be susceptible to criminal eyes, you probably lock your iPhone with a four digit PIN. While even I could tell you that ‘1234’ isn’t the finest choice in password security, Daniel Amitay took a moment to see what his customers were locking their phones with in his free app, Big Brother Camera Security for the iPhone. The passwords were recorded anonymously, and Daniel takes a look at everything from the most common passwords to suspect birth years in his results. Heck, the guy even built “heat maps” of the most digits pressed.

Naturally, 1234 is the most common passcode: mimicking the most common internet passwords. To put this into perspective, these 10 codes represent 15% of all passcodes in use. Most of the top passcodes follow typical formulas, such as four identical digits, moving in a line up/down the pad, repetition. 5683 is the passcode with the least obvious pattern, but it turns out that it is the number representation of LOVE (5683), once again mimicking a very common internet password: “iloveyou.”

With 15% of all passcodes represented by just 10 of these common passwords (out of a possible 10,000), Daniel concludes that 1 out of every 7 iPhones can be unlocked if a thief simply went through the list. Dear commenters, I now ask you, “Do you use one of these common passwords?” The results are fascinating, and I encourage anyone interested in keeping their iPhones secure to hit the source link for lots of juicy details.
