Enabling the "Passcode Policy" allows customers to enable screen lock on groups of devices or individual devices. All you have to do is set rules or parameters for the password like length, number of attempts and type of password. You are not able to set the passcode for the device from here. Once "Passcode Policy" is enabled, users will be prompted to set a passcode on their devices. The user is able to make his own password, however it must abide by the rules set under "Passcode Policies".
