My account was hacked tonight. I've had an authenticator for months and no one has access to it but me. Its on my keyring and kept either on my desk infront of me or in my pocket at all times. So it appears I wasted my money on a useless security device. GG Blizz, you useless bastards. Now I have to wait and HOPE some idiot at customer support answers my request, changes my password so I can get back on, and recover all my items and gold, which I KNOW are gone by now. I had almost 8 eighties, a massive stockpile of gold and mats for every profession divided up amongst a half dozen characters on my main server, not to mention I had spent months gearing out and enchanting a number of them to their best in slot.
If you've got an authenticator, you might as well throw the damn thing away because apparently Blizz makes useless crap now.
