I ended up just buying the Blizzard Authenticator from their site the other day. Hell its $6.50 with FREE shipping. Why WOULDN'T a boxer buy it? We have 2-5 times as much to lose and it only costs $6.50 for an authenticator that will work for ALL accounts. Takes about 10 seconds to set up and then adds about 2 seconds to your login time when you multibox, but will prevent you from ever having your account hacked. Plus, most likely it will work with future blizzard things like the new battle.net that will work with Diablo 3, etc.
