I have my 5 accounts across 5 separate battle.net accounts. The same authenticator can be linked to all 5, and then I can broadcast the same single code to all 5 when logging in.

If you have 5 accounts on 1 battle.net account, then you have to wait for a new code to generate every 30 seconds for each account.
