How to change your mobile device's passcode

iOS

• Go to Settings > Touch ID & Passcode. On devices without Touch ID, go to Settings > Passcode. If you have an iPhone X, go to Settings > Face ID & Passcode.
• Tap Change Passcode.
• Enter a new complex* six-digit passcode. (Note that iOS 11 devices may only have the option of creating a custom alphanumeric code listed.)

Android

Please note that Android devices do not have one standard way of changing your passcode. However, changing your passcode is usually listed in your device’s Settings. These are general instructions to guide you, but they may differ slightly from your device. We recommend looking up instructions to your specific device if the guide is not sufficient:

• Tap Settings.
• Tap Lock screen.
• Tap Screen lock. If presented, enter the current PIN or Pattern.
• Tap PIN. 
• Enter a new complex* six-digit PIN, then tap Continue.
• Re-enter the complex six-digit PIN then tap OK.

*What is a complex passcode?

A complex passcode or PIN includes numbers that:

• Are not ascending or descending (e.g., 123456 or 654321), and;
• Do not have more than two consecutive repeated digits (e.g., 143333)
