Authenticator Change Authenticator Change

To help keep accounts as secure as possible, we've recently changed how authenticators can be used. Going forward, authenticators can now only be associated with one account at a time. No changes are being made to how many game licenses a single account can support. You can still have multiple World of Warcraft accounts under a single account, for instance, and all game licenses linked with a account will still be protected if an authenticator is in use.

Those of you who currently have more than one 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 accounts for any reason, you won't be able to reattach it if it's already associated with another account.
