If you ever (for any reason) remove your authentication app/device from your account, change your password immediately BEFORE you do so. Moral: write down your mobile authenticator code and key, and keep it in a safe place, JUST IN CASE you lose or upgrade your iDevice.Įdit: adding EmeraldArcana's tip on the first post: If you want to have the Mobile Authenticator working on two iDevices, you can do that using the 'restore' function, and the security code of the working Authenticator, then both devices will generate the same codes. Note: I had once arrogantly deleted the authenticator app on my old iPad, and then rejoined WoW and needed it again, and the newly downloaded version still generated the 'same' security code for that iPad, so deleting the app and reloading it later isn't necessarily a problem.

That process went nowhere for me.Įventually I called Blizzard Support (on their Australian number, yay), and within a few minutes, after some exhaustive 'prove you are you' interrogation, they were able to revoke my old authenticator, add my new authenticator app serial number, and wait for me to successfully logon to (which I could, yay).

There is an option on the site to follow the 'I have lost my authenticator and want to remove it from my account', but it's horrible, and demands 'photographic evidence' of 'government id' (what ever the hell that is!). Yesterday evening, when I tried to register my copy of Diablo 3, I needed to logon to, and - surprise surprise, my iPad authenticator app was spewing out numbers that didn't match the -serial number- of the authenticator attached to my account.
BATTLENET REMOVE AUTHENTICATOR SERIAL NUMBER
I haven't played WoW for ages, since then, I upgraded my iPad to the latest model ('retina' display, camera, more RAM, faster processor, apple gremlins controlling my brain, etc), I had never written down the dozen digit serial number of my Mobile Authenticator app (because, you know, who cares and all that).
