Option to tie your account to multi IP

You could always use the security token/app to stop this from happening. I believe it actually tells you that when you receive your email.
It's only an extra 5 seconds of your time to login, worth it.

Cant because me and my brother share his account. I have my own account but he chooses not to register his 1 type password and would cause issues trying to take control of his account from my house up the street.

edit:
Do they allow you to register 2 1 time password tokens on the same account? That way I can use my token and he could use his own?

Oh an you should never ever share and account. That is rule #1 to prevent being hacked.

Sorry you can't have more than 1 security token active on 1 account at any time.

SE has a memory of what IP's you use and should only require you to pass security checks once per different IP. If you are getting more than one security check everytime you are trying to log in (at the same address) then it is likely that the network is set to refresh or rotate its IP address. (can also happen if you reset your router from some providors). If your IP is always the same then you might want to contact SE if you keep getting flagged.

FYI I have another account with no authenticator and I have only ever needed to pass security checks once on each static IP address, but everytime on a revolving IP address.

Hope you can find a solution to your situation.

Can't. It sucks. Especially considering you can do it with BNet and their iPhone app. Both my iPhone and iPad generate the same codes for my Bnet account. Its because of how the (MUCH BETTER) recovery system works for their apps.
