My Blizzard account got hacked today, and after going through the process to get my stuff back, I stumbled on the fact that they now have a mobile authenticator on the android market. It's free and hopefully keeps your account a whole lot more secure. Just download the app and register the serial number to your battle.net account, it's super easy.
Only applicable if you play World of Warcraft or Starcraft 2 or something, but it's free and on your phone, so it's pretty handy.
