Did Google drop support for this? Where is the Move to a different device in authenticator? From what I saw it used to be there  but is not there any longer. I have a bunch of other applications/sites/etc that use 2FA that I have loaded in GA  but there is no way to move it from my old phone to my new phone. The Google support document """"""""Using a new phone to receive 2-Step Verification codes"""""""" references """"""""In the section for the Google Authenticator app  click Move to a different phone."""""""" which is missing. Change phone only adds Google  leaving all the other accounts on my old phone (and what if I didn't have my old phone?). Moving to a different phone including all of the other 2FA entries was there in the past but unfortunately no longer. Useless....""
