Perhaps I could have phrased it better. I meant don't let me disable 2FA without first authenticating using 2FA. So ignore any emails to support, 2FA reset links, secret questions, pleas for help, and anything else that would have you think that I no longer have access to my 2FA device and backup codes.

Changing devices is allowed but to do so I would authenticate using my password + 2FA prior to doing so.
