XF 2.0 Two step verification problems

I think I have a big problem. Some time ago I opened a community with XenForo and create an extra account with administration permissions. The main administrator account is protected by two-step verification with google authenticator but today I just lost my cell phone where I had the App and the photo with the extra codes. I am the administrator of the server where I have hosted XenForo. How can I recover the account?
 
If you don't have access to the 2FA codes to log in to the ACP, then having the option there to disable it would defeat the purpose.
