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. So you should activate the iPhone Passcode and set your own numeric or alphanumeric code to protect your data. We explain how to set or change the iPhone Passcode and we also explain the difference between the iPhone Passcode and the SIM PIN.
Purpose of the iPhone Passcode
A passcode or four or six digit code is an extra layer of security for your iPhone. Enabling passcode security makes sure that no one can access your personal information or 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 Passcode also makes sure that your kids don’t go on a (possibly expensive) shopping spree in the App Store or on Amazon.
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.

Passcode vs. SIM PIN
Do not confuse SIM PIN and Passcode as the two have completly different functions and are required at different times except for rebooting your iPhone. Then your iPhone will ask for both SIM PIN and Passcode after booting up, unlocking the screen or applying an iOS update and after fully resetting the device.
Your Passcode protects your personal data on your iPhone by locking your screen, when not in use, so noone can get access to your personal information.
Your SIM PIN protects your SIM card and thereby costs charged to your SIM card through calls and mobile data.
If your Phone came with a SIM card, chances are you already have a SIM PIN. Your carrier might have given you a document with the code on it. Should you want to disable the SIM PIN for your iPhone, simply follow this guide to change PIN on iPhone or disable your SIM PIN.
