firefox two-step authentication always fail because of wrong recovery code

more options

I am keeping trying to set up a two-step verify on my firefox account, but stuck on the last step of input the recovery code, even if I input the right recovery code, it still tells me I entered wrong code.

Chosen solution

You entered the full set of recovery codes at once. You only need to use one, first unused, of the 10-digit recovery codes. Each code can only be used once, so you can generate a new set if necessary if you run out of codes.

This is not the point, after scanning the QR code, the 6-digit code does not work and when you try to enter addons, it asks to connect it again and again, if you click to refuse, it does not let you into the office

After scanning the QR code to setup 2FA you need to enter a 6-digit code provided by an authenticator app on a mobile device to confirm that the app is working properly. If that code isn't working then it is possible that the app isn't compatible with Firefox. You can possibly scan the QR with your barcode scanner and open the authenticator app that way to see if that makes the app generate a working code.

You can try a different app or an extension in Firefox and compare the generated TOTP code.

Thanks a lot, It really helped, and for security reason, I have updated my 2FA code.
