We all have stories of knowing someone who had their account hacked or have been hacked themselves. The authenticator is inexpensive, supposed to reduce the chances of being hacked and Blizz says it is cheaper for them to market authenticators cheaply because it costs them less than having to recover accounts all the time. I was thinking of using the mobile authenticator simply because it uses more digits than the fob. However, I have heard stories of accounts getting hacked even with an authenticator. Of course then accusations fly that "MY ACCOUNT WAS HACKED BECAUSE OF THE AUTHENTICATOR!!!" What are your experiences with the Blizz authenticator? Do you use it only at home or do you feel brave enough to use it on friends' computers? Do you use the Blizz fob or the iPhone/Touch mobile authenticator?
