It’s always good to have a passcode on your iPhone, because you never know when it could fall into the wrong hands and have your sensitive information revealed. Using a strong passcode will prevent the stress of relying on Find my iPhone should your precious baby get stolen or lost.

The maker of the free app Big Brother Camera published some anonymously collected stats of the most common iPhone passcodes. The results might shock you as ‘1234’ topped the charts of the most commonly used passcode! The developer Daniel Amitay goes on to describe the flaw of formulaic passwords:

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.

Did your passcode make the Top 10? What’s your passcode (don’t worry I won’t tell)? I’m glad my choice of ‘4321’ is still safe!
