iOS7 came with the new Activation Lock feature as an extra layer of protection that will pretty much prevent turning off Find my phone, resetting, erasing or reactivating the device meaning preventing theft, however if not set properly, you could lock your own device!
One of the new security features of iOS7 is the antitheft Activation Lock which basically makes it difficult for anyone else to use or sell your iPhone, iPad, or iPod touch if you ever lose it. Of course this could prevent or lessen theft rats as there would be no use of the stolen device if he can’t reformat it. The police have been encouraging people to upgrade their iPhones because of it.
If you have Find My Phone turned on, you must have the password associated with its Apple ID in order to turn off Find my Phone, erase or reactivate the device. This is great in theory, but in practice the strategy relies on some advance planning by device owners to prevent a disaster.
The feature is automatically activated once you upgrade to iOS7 and turn on your Find My Phone, so don’t spend hours searching for its button. In order to setup Activation Lock you have to upgrade to iOS 7 on your iPhone or iPad and then go into Settings > iCloud and then make sure Find My Phone is turned on.
The feature looks so good so far, but it is going to be your worst nightmare if you forgot or lost your Apple ID. In a nutshell if you forget your password and cannot reset it, you will lose access to your Apple ID and may be unable to use or reactivate your device. So, you should write down your password and keep it somewhere safe where you can get it anytime.
