What is the best way to deal with having an authenticator?

[Peregrine]

I just checked and the option to require a code for every login is unchecked.
The bnet application? Do you mean the authenticator app? I am already using that one.
Or do you mean the actual Battle.net app that allows to chat with contacts?

Yeah, the bnet application. You should not that face such issue afaik. Do note, I mean the actual website login account and when you login to their website, under the security you'll find that option that I've posted earlier.
