How to enable activation lock on iPhone or iPad

The function of activation lock is an innovation in iOS 7 that allows you to remotely wipe all data on your device if your iPhone, iPad, or iPod Touch is lost or stolen. This feature has been so popular with iOS device owners that it is now active on 78% of iPhones.

After Activation Lock is started remotely, a message appears on the device screen with details of who and how to return it. Agree, it is very convenient if you suddenly forget your iPhone in a cafe or taxi. When you return the device, you only need to enter your Apple ID, which will reactivate your iPhone or iPad and give you full functionality. At the same time, the person who had the device all this time will not be able to work with it.
