How to Change the Password for an iPhone

By Adrian Grahams

Setting a password for your Apple iPhone can protect your data and prevent unauthorized calls if the phone is lost or stolen. Anyone who tries to use the iPhone must enter the correct password, known as a passcode on the iPhone, as soon as they switch on or wake up the device. Changing the passcode regularly is a sensible security measure to prevent unauthorized access to your iPhone. Alter the passcode through the Apple iPhone's Settings menu.

Switch on the Apple iPhone.

Tap "Choose Settings" on the iPhone display screen, followed by "General" and "Passcode Lock."

Enter the current passcode when prompted. This displays the "Passcode Lock" settings page.

Tap the "Change Passcode" option on the screen.

Enter the current four-digit passcode in the "Enter Your Old Passcode" dialog box.

Enter the new four-digit passcode and then re-enter it when prompted to confirm the new password. This displays the "Passcode Lock" settings page again.

Read through the other options and select your preferences with the drop-down menus and sliders. You can choose the amount of time that elapses before the iPhone requires you to enter the passcode.
