I want to understand better about Apple's activation lock. My understanding is, Apple is linking an iDevice with your iCloud account, so in the event the device is stolen/restored/reset, one has to verify the iCloud account first. It is enabled when Find my iPhone is enabled. Question, is this linked to the passcode? Scenario: An iDevice doesn't have a passcode, but find my iPhone is turned on. What is the ramifications if the device is stolen? Let's say two factor authentication is enabled on the iCloud account.
