Worried about local hackers? Like leaving your laptop behind in the coffee shop while you take long, leisurely trips to the bathroom? We wouldn't be so self-assured. Turns out there's a gaping security hole in the FaceTime beta , which allows anyone with access to your computer to change your password without knowing it to begin with, as well as peep and edit your security questions and answers. It would be nice if signing out of FaceTime would protect you, but unfortunately the app seems to have a lock-tight memory on your password, so it's easy for anyone to open the app and sign-in again. Hopefully Apple will fix these holes quickly, and until then we recommend uninstalling FaceTime or choosing your friends very wisely.
