I dont think Jimmysalian-2011 understood your question.
What i did to stop the annoying popup was go to the settings in Authenticator, scroll way down and find "Choose info to autofill". Then in there i changed the top option of "Addresses" to "autofill only". So it wont ask to store any new ones, but will ask if you want to autofill ones you already have.
Also, you can still manually add addresses to authenticator if you need to as well. It is along the bottom in main window where your codes are. Tab labeled "Addresses".
