Hi, I'm trying to recover my FF account using the recovery key. I used Google Authenticator for 2FA, reset the phone, found out GA doesn't back 2FA accounts up remotely. That was a few years ago; I gave up and went back to Chrome. Trying again to regain access to my FF account now, if possible. I don't have the backup codes, but I do have the 32 character recovery code, but I'm getting this error (screenshot) trying to use it. I tried the key with spaces (8 4-character blocks) and without, got the error both times. What am I doing wrong here?

If your 2A fails and email reset code don't work that account is a lost account at this point. There's nothing forum users here can help to recover account or codes.
