Unlinking an Authenticator
If you do not want to use an authenticator any longer, you can "Unlink" (two-factor authentication app) or "Deactivate" (two-factor email code authentication) the selected authenticator. Log into your account and follow the steps in the section "Two-Factor Authentication" on your account page.
Keep in mind that you can only unlink your account from an authenticator app with a valid recovery key or a recovery TAN! In case you have lost access to the account's email address, you will also need your recovery key or a recovery TAN to unlink your account from two-factor email code authentication or to change the email address of the account.
If you have lost your recovery key and have a registered Tibia account, you can order a new recovery key using the Lost Account Interface on the website.
