I think declutterqueen is referring to the following screen, where you enter the authenticator 6 digit code. I believe this screen should contain fall back options for alternatives such as:Pass keysEmailText etc.But for some reason they are not visible. Without the fallback options, you may lose Trade Me account access (as per declutterqueen's experience). Google's equivalent login screen, has a link called 'Try another way'. That's useful because you can select alternatives, if you can't use your normal authenticator for any reason.
