WHERE IS IT?
Trying to sort this authenticator out just so I get some free bag space and this whole procedure is incredibly annoying.
You get it from the authenticator app (or possibly from the physical device if you have some old one as those haven’t been sold in ages).
Support site has more instructions if you need to add authenticator to your account:
You can google WoW Authenticator and buy them pretty cheap, well it used to be. Now they’re a little scarce, so you’ll be spending around 20local golden coins.
Or, you can download the Battle.net Authenticator for free from Google Play for Android and Apple Store for the iPhone.
Sorted the issue out, wasn’t very informative. Asking me for an auth code when I didn’t have one. When I tried using the app, the code wouldn’t be accepted.
Needs a fix.
