“Two-step authentication, such as a message to a mobile device, is still not the same as fully-fledged two-factor authentication. While the extra security is welcome Ferguson said more can be done to secure user accounts. Two-step authentication means that even if an attacker has the username and password for the account they cannot access it without the extra code. “It’s really great to see Apple extending its two-step authentication to cover more services, particularly person-to-person communication services such as these, which have been so widely abused in the past (Facebook, Skype etc),” said Rik Ferguson, vice president of security research at Trend Micro. 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.
