I don't think that's accurate. I've changed phones multiple times and the worst I had to do was find my list of 10 recovery passwords to use one to get in and change the phone I use with Authenticator.

Usually I would just login and add the new phone.

Agree, I've lost phones with many of my 2FA tokens on it, I pulled out my backup codes and got back into all 10-15 or so sites which I use 2FA on.

With the exception of a SMS to a registered phone recovery method, if I can loose my 2FA token, and loose my backup codes, and still access my account, then the 2FA implementation is IMO deeply flawed.
