How to Use a 4 Digit Passcode in iOS 9

Apple periodically releases new versions of its iOS software for iPhones, and many users will eventually install the most current version available for their devices. Each new iOS version brings about some new features and changes, many of which are meant to improve security on the iPhone. So, after updating to iOS 9, you may have switched from a 4-digit to a 6-digit passcode. It may have initially seemed like this was a new requirement, but you still have the option to use a 4-digit passcode if you would prefer.

Our guide below will walk you through the process of changing from your current iPhone passcode to the simpler 4-digit passcode that you were likely comfortable and familiar with in earlier versions of iOS.
