you can use the same number for all your clients. I launch all my windows. type my password. then the box pops up. I use the same key for all 5 of my accounts. Since I am typing it in all at the same time you only need 1 button press on the authenticator. If you merged your accounts onto battlenet. I am not sure how that affects your login since you have to choose which acct.
If you have your remember account name button checked, you'll need to click the drop down on each window to select which account to log into. Select account -> Pass -> Authenticator -> Profit.
