Dear Mozilla Support Team, I am writing to request your assistance in recovering my Firefox/Mozilla account. I have unfortunately lost access to the authenticator app used for my Two-Factor Authentication (2FA). Furthermore, I do not have my backup recovery codes saved. However, I am the rightful owner of the account and I currently have full access to the registered email address associated with it: riadchowdhury908@gmail.com I understand Mozilla's strict security and privacy policies. Is there any way to verify my identity through my registered email address or perform a manual review to disable the 2FA on my account? I only need the 2FA disabled so I can log back in and set up a new authenticator. I am ready to provide any additional information needed from my email to prove my ownership. Thank you for your time and support. I look forward to your response. Sincerely, Riad Chowdhury

Good morning,

I was randomly signed out of FireFox this morning. When trying to sign back in, it asked for the 6 digit code from my authenticator app. I looked on every authenticator app I have and don't see a mozilla or firefox account. I only have 4 backup authenticator codes left. How do I find the code in the authenticator app and which app would it be? Also, How do I get more backup codes? If I am unable to sign in to FireFox in the future because I don't have the correct authenticator app or enough backup codes, it would be painfully devastating for myself and my work. I don't want to ever be in that situation. Any advice would be greatly appreciated.

Got a new pc.. Tried signing into Firefox.. Asked me for 2 step verification.. No idea where the app or backup keys are.. Im still signed in on my phone tho.. Anyway to disable 2 step? I tried through my phone and its taking me to same page where i need 2 step authentication.

Hi,

I have been locked out of my account and the two factor authentication does not work any longer. This is the first time this has ever happened to me.

I do not have a Backup Authentication code, but I am logged into Firefox on my mobile. Unfortunately, the iOS version does not have the ability to change my Security settings as instructed by the guide.

Can you please help me gain access to my account?

Thanks and regards,

Bernard

Greetings team,

I;m using Firefox and Mozilla services from beginning, since I was child. I noted what MFA is not working, on my both accounts. it was my early guess also since last year but i fought it was my problem. No after resetting and getting notification what password is not correct makes me guess something is off. i might be wrong but looks like internal problem, maybe a breach what no one knows. what can i say from my side, as an IT company director and IT person. i can exclude all my thoughts about my side, since i changed and reinstalled everything on my devies. got fresh OS and hardened every device. problem still exists. maybe someone could check my accounts and internal settings for firefox security on accounts and MFA. since codes are not valid. had to disable mfa on my both accounts.

FIDO2 Security Key (e.g. Yubikey) Support is entirely broken on Firefox mobile and has been for weeks. Screens that should pop up an interface to use my security key (e.g. after I've typed my password in to Google, in order to do multi factor auth) simply do not show the pop up. This is an absolute P0 issue that makes the browser entirely worthless as a default browser on a device, as many apps want to use Webauthn through the browser to do FIDO MFA. I will be forced to switch to an actual functional browser if this is not fixed soon.

This is on a Pixel 10A: 148.0.2 (Build #2016148295), 15542f265e9eb232f80e52c0966300225d0b1cb7 GV: 148.0.2-20260309125808 AS: 148.0.1 OS: Android 16

I downloaded the authentication app because my Firefox browser told me to. But after I got done subscribing to the app it like won’t let me do anything and It’s just stuck on the same page the page’s says connect all emails or something. What should I do?
