The problem with keyloggers and other methods of account theft has been well documented here at WoW Insider, and it seems like a constant problem. Even the most conscientious of players has fallen prey to it. However, at the Worldwide Invitational, Blizzard is introducing a little piece of hardware that could make those problems vanish. Say hello to the Blizzard Authenticator.

The Authenticator is a small piece of hardware that you can associate with your World of Warcraft account. Once the Authenticator is associated with the account, you will need it to log on. Every time you log on, you press a button on the Authenticator to generate a six-digit code that you must input to log on. Since only you know the code, and it's generated apart from your computer at the time you're ready to log on, it will be safe from trojans, keyloggers, and other hacks.

The Authenticator will be available at the WWI to start, then eventually at the Blizzard Store. The starting price being quoted by Blizzard is $6.50 -- a small price to pay for safety from a ransacked bank and naked server transferred characters, for many.

Is this the big announcement though? It's possible, of course, but we like to think there's more in store at the WWI. Stay tuned here, and we'll let you know.
