How to Change the Passcode on the iPhoneby Leigh Thompson
Because your iPhone can contain very personal information, it's important to put a passcode on your device to prevent unauthorized use of the device. By default, a passcode is not enabled on the iPhone. You can use a simple 4-digit passcode or you can set up a more complex passcode that consists of letters, numbers and symbols. Enable a passcode on your device through the Settings app.
Tap the "Settings" app.
Tap "Passcode Lock."
Enter your current passcode.
Tap "Change Passcode" and then enter your old passcode again.
Enter a new passcode and then re-enter the new passcode for verification.
Press the "Home" button just below the iPhone touchscreen to return to your iPhone home screen.
- check Tap the toggle to the right of "Simple Passcode" on the Passcode Lock screen until "OFF" is highlighted to create a more complex passcode with numbers, letters and symbols.
