I added 2FA to my account on 10 October 2021, and recently bought a new phone with a fresh Authenticator app. I have all my backup codes saved already so I thought it wouldn't be any worries.
I was wrong, I've been facing this error for all the 10 different codes:
Backup authentication code not found
I only have one Firefox account with 2FA, so I'm 100% confident this is the right account. I have access to my email associated with the locked out Firefox account and I can see the email mentioning that I activated 2FA on 10 October 2021, and there are no emails beyond that regarding my 2FA.
I am a developer who have published Firefox Addons - so I am not able to just create a new account, I need this account specifically.
I have the following info:
- Email
- Password
- Backup codes (that don't work, I can provide screenshot of the codes upon request)
- Gmail Access associated with the Firefox account
Help really appreciated,
Tomas
