Apple enables two-step authentication for iMessages and FaceTime

Samuel Gibbs, The Guardian:

The login protection was added to Apple’s iTunes and iCloud accounts in March 2013, meaning Apple users who have perviously logged into a Mac, iPhone or iPad with their Apple ID were already protected by the extra security.

Now the same service has been activated for two more of Apple’s services, meaning that if users log out of their FaceTime or iMessage accounts and attempt to log in again, or log in on another machine, they will require a security code to confirm their username and password.
