4. You will see a message stating that all sessions will be terminated, and local users are disabled. Logging in as administrator with your account will still be possible. Click Next.
5. Enter the message to be displayed on the lock screen. If you lost your device, it makes sense to specify ways to contact you. If you simply block your home or work computer, I am sure that you will be able to come up with a decent message.
