Unfortunately, our account custodian lost his cell phone, so he lost the saved 2FA verification
we can’t find the backup authentication codes and don’t have a signed-in device.
we register a new Mozilla account through business email
Now we can’t manage our previous add-on, can we get back to our previous account or sync the add-on to the new one?
Best
Hello @vinn, sorry to hear you are having issues.
Is your issue one of the use cases covered here?
Thanks – Ed
It just occurred to me that link I provided may be where you got your original info 
- sorry if that’s the case.
First of all, Edward, thank you for your reply.Yes, This is where I obtained the original information. The original text mentioned, “You can however create a new account with a different email address to begin syncing again.” However, I couldn’t find the place for syncing, so I’m here to seek help. Thank you again in advance.
No worries, I have a question out to an internal team. Will post back here as soon as I hear back, thanks for your patience!
