In order to detach the authenticator from this Battle.net account, you need to provide two consecutive authentication codes. To do this, retrieve a code from your authenticator and enter it in the topmost of the two fields below. Wait approximately 30 seconds, then retrieve another code and enter it in the second of the two fields. After entering the second code, click the "Remove" button below the fields. You must click this button before the codes expire for the authenticator to detach successfully.
