Hi, trying to sync to a new phone, scan the QR on pc and on phone get "open your authentication app and enter security code" Whats the app? I get no text on phone and no email to FF account email, or any of my other email accounts, all spam and junk checked. I did get to the ten number authentication once, and tried 2 of my codes, and it would not recognize them either. I didn't want to keep burning codes. Thanks.

Hi

The authentication application is one that you would have installed when you set up second factor authentication for your Firefox Account.

This support article should help:
