I have a super user admin who is locked out because of 2 step verification. I went into the dashboard and his profile shows 2-step verification is disabled. All user groups were set to no for this as well.
I can see no way to unlock him so he can access the forum. He cannot even look at his own profile.
I also tried adding $config['enableTfa'] = false; to the end of the library/config.php and this doesn't seemed to have done anything at all.
