Knowing how to change passcode on iPhone is perennially useful for all iOS users. If you think someone might have been snooping over your shoulder to see your current passcode, whether that's an unruly sibling or a nefarious stranger, changing your lock screen code is vital.

It's also a good idea to change your iPhone's passcode every once in a while anyway, whether there's a direct security concern or not. 

Handily, changing your passcode is extremely easy to do. Bear in mind, though, that you will need to know your existing passcode in order to create a new one. If you don't know your current passcode, it's a good idea to get support from Apple. If you're not sure how, read our guide on how to make a Genius Bar appointment.
