But I know that if I cancel the 2FA and install it again, I'll get 8 fresh new codes. I still have six or seven backup codes valid, I don't want to waste them. How would you suggest that I should proceed? Should I enter my installed program, cancel the two-step authentication, and then install it again? I typed the security code from Google Authenticator, and then received the same response as with the laptop: It says: 'Open your authentication app and enter the security code it provides.' Modified September 21, 2023, 6:51:20 AM PDT by Eldad S-firefox I installed the 2FA on my main computer, which runs Win 11. Why are there no passwords etc? Aren't they automatically drawn from my usual (existing) account? My second question: I finally managed to enter my account with one of the eight backup code. My first question is why does Firefox reject the codes received from Google Authenticator (do I have to cancel my 2FA and define it once again? but I did everything by the book, with GA, and it seemed fine the other day). I had to use one of the backup codes (out of the 8), and managed to enter my account on the laptop, but none of the logins and passwords were found there (it's empty). I'm now trying to enter Firefox on my laptop.Īfter typing my password, when I try to enter one of the generated Google Authenticator codes, I constantly get a response 'Invalid code'. I scanned the barcode by Google authenticator, to make it my code generator.
