2015 iMessage and FaceTime get two-factor authentication


Apple has improved the security of FaceTime and iMessage, its voice/video and multimedia chat communication tools. The services received two-factor authentication as an option for users to enable, meaning that even if someone uses their Apple ID email and password to enable iMessage or FaceTime on a new device, they’ll still need to use a PIN from an existing trusted device to gain access to those services. If you’ve previously enabled two-factor for iCloud, it’ll also be enabled to FaceTime and iMessage. The additional level of protection applied to these services helps ensure that people will have a harder time grabbing potentially private images from your iMessage history, or pretending to be you via online communication methods.
