The thing about the Authenticator is that the six numbers that appear on the screen are not always consistent. They sync up numbers in a Blizzard database somewhere and refreshes on a regular basis. I haven't sit down with mine and watched it to see how long, but I'm guessing that the number remains current for about thirty seconds or so.So, even if a keylogger somehow manages to capture all of that information -- username, password, and the six-digit Authenticator number -- it would only be current until the number was refreshed. Unless the potential account thieves immediately got that information and then used it, they would find the Authenticator number out of date.I also discovered that the Authenticator ties into accessing my account information on the official World of Warcraft website. I tried to log in from a computer other than my own (next to which sits my Authenticator) and found that I couldn't log in without that number on hand. Assuming that the Authenticator remains tied to my account that's pretty good!
