- Tap 6-Digit Numeric Code to use a numbers-only passcode that contains six characters.
- Tap 4-Digit Numeric Code to use a numbers-only passcode that contains four characters.
Step 6: Enter a passcode. Use the keypad at the bottom of the screen.
Step 7: Re-enter your passcode. This verifies your passcode.
