How to Change Your Passcode on an iPhone
Picking a memorable passcode for your iPhone is the best way to secure it from prying eyes and thieves. You don’t want to be in the situation of having forgotten your iPhone passcode, thus you should go ahead and change the default. Four digits are better than none!
Purpose of iPhone passcode
A passcode or four digit PIN is an extra layer of security for your iPhone. Enabling passcode security makes sure that no one can e.g. place a call from your iPhone without your permission. Everyone should at least have a basic passcode, unless the device never leaves the house. Setting a PIN also makes sure that your kids don’t go on a (possibly expensive) shopping spree in the iTunes App Store.
Your passcode plays a role in protecting your data, as the iPhone will ask for it after booting up, unlocking the screen or applying an iOS update and after fully resetting the device. Setting up a passcode is also beneficial to users of Touch ID, as you need a fallback solution for situations in which the fingerprint sensor does not work.
