Is it possible to hack facetime call? Me and my girlfriend are using facetime regularly for talking. I'm worried if anyone can hack our Facetime calls and record our videos? Is it possible? How safe is Facetime?
FaceTime calls are encrypted sufficiently for most anyone's needs. FaceTime's encrypted stream acts underneath any other WiFi encryption that might also be present. If you feel that end-to-end data streams encrypted with unique keys for each recipient is safe, then I'd say have fun with FaceTime.

Someone with special skills, tools and time could probably crack it, but you probably don't have a high enough profile to be worth the time/effort.
