Blizzard is changing up the security on their authenticators
a bit. This isn't a major change and shouldn't affect that many people. Starting now, if you happen to have multiple Battle.net
accounts (not multiple WoW
accounts under one Battle.net account), then each account must have its own authenticator. This means if you have separate Battle.net logins for firstname.lastname@example.org
and you want to use an authenticator, you'll need to buy two. If you've just got email@example.com
and all of your games are under that Battle.net login, then you're perfectly fine.
This is not retroactive. If you already have two accounts linked to a single authenticator, everything will still work as it does right now until you unlink that authenticator. The full blue post detailing the changes is behind the cut below.
Lylirra on the authenticator changes
To help keep Battle.net accounts as secure as possible, we've recently changed how Battle.net authenticators can be used. Going forward, Battle.net authenticators can now only be associated with one Battle.net account at a time. No changes are being made to how many game licenses a single Battle.net account can support. You can still have multiple World of Warcraft accounts under a single Battle.net account, for instance, and all game licenses linked with a Battle.net account will still be protected if an authenticator is in use.
Those of you who currently have more than one Battle.net account associated with a single authenticator will be able to maintain your existing setup without needing to do anything. This change will only affect new authenticator attachments. But, if at some point you decide to detach the authenticator from any of your Battle.net accounts for any reason, you won't be able to reattach it if it's already associated with another Battle.net account.

Like I said at the beginning, this isn't something what will impact too many people, as a majority of players will only have a single Battle.net account, and all existing authenticator setups are grandfathered in.
