The Scramble Passcode function is the option for a user to input random numbers before or after the correct passcode (less than 12 digits in total).

With the Scramble Passcode function enabled, you can make the passcode even more complicated and difficult. It is harder for others to spy on your actual passcode when you are entering the passcode.
