Our company uses this email address to manage a Firefox add-on. Recently, we lost access to the 2FA device and the backup codes we had. When we tried entering the backup codes, they were unexpectedly marked as invalid.

Is there any way to recover the account using just the email address? We urgently need access to manage the add-on.

I appreciate your help!
