Is there any way to prevent Battle.net from locking an account while traveling

I have a big problem with Battle.net. I play Starcraft 2 (Heart of the swarm) and I travel a lot (from San Jose all the way up to San Diego), sometimes even within days. I would still like to continue playing starcraft but everytime I come down I get my account locked for suspicious activity. And going through a reset and password change everytime is extremely frustrating.

Is there any way to disable this functionality. Or to set up a proxy on my computer to somehow download the game in san diego anyways without password change.

(everything on the computer in San Diego gets cleared as soon as I leave even if im going to be back in a day there is nothing I can do about it so dont include possibilities of resolving this problem in the answer. I also cannot take my computer when I travel)

Do you have a smart phone? Blizzard has an authentication app that lets you "validate" who you are.

It sounds like there is ghosting software as soon as you log off, but you have access to "install" applications when you are using it. You mention that you're downloading it every time. Why don't you copy the Starcraft 2 folder to a USB stick and then just copy it to the computer every time you are on it?

Starcraft 2 doesn't need to be installed in the traditional sense as you can just copy the folder to whatever computer you are using it on and just run the application.

The answer truly is to give support a call. The fact of the matter is, this kind of DRM is only in place as a blind default - good customer service representatives will take your convenience and patience as a customer into consideration far above strict adherence to the rules. They value you as a customer. Companies have learned a lot since the famous Spore DRM fiasco that Electronic Arts pulled so many years ago already. This kind of failure has changed the industry for the better, and Blizzard is already quite good with their customer service. In short - just talk to a real human being, and they should put a stop to this kind of issue.

If the app becomes a pain to use or you want to make it easier, you might want to take it up with Blizzard. As Southpaw said, real humans are more patient and the company knows more than us. Some technical features of an account (like overriding that lock) might exist if you ask them.
