I know I don't understand the internet, but if I have IP of 128.64.x.x and they want to steal my IP, so they make thier IP of 128.64.x.x. Why would the routers in America (where I am), route to an address in Asia when none of the 128.64 addresses exist?

Also, what about a hash of computer equipment that is sent to Blizzard is stored on your computer?

I don't think I would have ever trusted the phone authenticator. That is more marketing than insurance. Also, as some others have said, we are supposed to be smarter than the rest of the players, mostly cause we have more to lose (5 accounts, not just 1). So I would have used an actual authenticator (iphone, keyfob) instead of a system that is supposed to protect you.

I am not against being able to opt out of it. I just really like not having to type in a code each time I get disconnected.
