As simple as the concept is, the passcode required to access an iPhone was an important security advance when it was introduced with the first version of the device in 2007. Because the iPhone is essentially a handheld PC and can store so much sensitive personal information, Apple shipped the device with a passcode feature. The default passcode was immediately posted all over the Internet, but it’s easy to change. Users also have the ability now to turn off the simple four-digit passcode and turn on a longer alphanumeric passcode instead, which adds more security to the system.
