Apple adds two-factor authentication to iMessage and FaceTime

Apple has enabled two-factor authentication for both iMessage and FaceTime, providing users with additional security on top of just a password. After a user enables two-factor authentication, they will also require a separate, temporary PIN that will be sent to them via text message whenever they sign into either service.

Users can enable two-factor authentication by going to the My Apple ID page, signing in and selecting the two-step verification option under the "Password and Security" menu. Turning two-step verification will remove a user's security questions.

Two-factor authentication can also be used to protect iCloud backups.
