The Blizzard Authenticator is a small key fobno bigger than a stick of gum that has a single button and a small numerical LCD. That LCD will display a six digit code that has to be inputted into the game after your enter your password in order to login. Without someone having physical access to the device it becomes nearly. No matter what you do, there is always a risk something will happen and your account can be compromised. That is, unless you take advantage of one security "trick"that will secure your wow account far more than anything else out there. The first is that if you lose the authenticator then you'll have to contact Blizzard to get into your account.You can mitigate this risk by keeping it at your computer in a drawer or attached to something near your desk so you never have to worry about losing it. The second thing is that it does take you a few seconds more to login. Rumors abound that Blizzard has too many restore requests and too many hacked accounts to handle. It only makes sense that security like this be enforced in a game that is such a huge target.If you like more information visit the official site.But if you need to buy security wow goods such as wow gold, wow game cards, wow power leveling.
