Your Apple devices just became a bit more secure. iCloud and iTunes have had two-factor authentication for over a year, but now this security feature has arrived on iMessage and FaceTime for your iPhone or Mac.
FaceTime, Apple’s video calling feature, is available on iOS devices (iPhone, iPad, iPod Touch) and Macs. iMessage is Apple’s messaging service that gives users the option to send text/picture/voice messages. Two-factor authentication ensures your devices are protected against any attempt to hack into it and to enable it you’ll need to log into your iCloud account and enter your password and a unique code.
