Online games, especially popular ones such as World Of Warcraft (WOW) are regular targets for scammers.
Using trojan horses and phishing techniques the scammers, who range from kids looking to hijack accounts, to professionals looking to sell accounts for real dollars, are a constant menace.
Now Blizzard, the team behind World Of Warcraft, have come up with their own physical token, much like the paypal key I wrote about last year.
Currently costing $6.50, the Blizzard key can be found here.
With this device your account will be safe, even if your WOW password is stolen by a trojan or phisher, as they will not be able to login to your account without it.
