Firefox Community Forum

Hi All,

I am trying to setup 2-Factor Verification for my Mozilla account however every time I enter in the 6 digit code it shows up with "Invalid or expired code. Check your authenticator app and try again."

And I am positive I am doing it right. As I would normally do it; scan the QR code, enter in the 6 digit code.

If anyone has the same issue or solved it, please let me know.

When setting up 2fa. I scan the QR code. Enter the 6 digit pin generated by google authenticator. Download my backup codes and enter 1 when prompted then firefox says sync time and try again. I am running Ubuntu and have an android phone. Ubutu is set to automatic date. time and timezone. My phone is also set to automatic date&time. I have enabled seconds display on Ubuntu and phone the are synchronized to the second. I have tried this on multiple computers. Google authenticator works with all 9 other 2fa logins I use it for. I have tried many times and asked AI what I'm doing wrong Grok said I am not doing anything wrong after walking through the entire process. I have tried clearing cache and deleting cookies, signing out and back in without success. Please help I use firefox as my password manager and love it but want it to be as secure as possible.

thank you very much. Thomas

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

HI I want to change my Firefox Account email to a new one because my email [email removed]@gmail.com has been hacked and i want to change it to my new email: [email removed]@gmail.com

I've been trying to set up 2fA on my firefox account, the whole process seems to work, I downloaded the backup codes and entered one to confirm and then got confirmation that 2FA was enabled (see screenshot). However, after reloading the page 2fA is shown as being disabled and indeed if I try to log out then in again I'm not asked for a code. I've tried this a couple of times now and it does the same every time. The auth app I'm using is Aegis.

Does anyone knows why this is happening ? Thanks.

[Edit: I just saw that after each time I tried to set it up, in "recent account activity" I add an error saying "Two-step authentication failed" which doesn't really makes sense...]

Hi everyone,

I have been stuck for 3 days now and tried everything to get pass the authentication process.

I want to submit an Add on. On my profile page, 2 step authentication is enabled.

When i click submit new add-on, i am directed to the Enable two-step authentication page anyway. So ok i'll do that:

"Scan authentication code to continue to ⁨Add-ons⁩"

So i use google authenticator. And im able to continue.

Then im presented with "Save backup authentication codes", so i download them and store them.

PROBLEM:

On the next page, in need to "Confirm backup authentication code". ANY code i try, that was given to me in the previous step, doesn't work.

Error: There was a problem confirming your backup authentication code.

• not using caps or whatever
• no spaces in there
• tried all the codes
• tried different browsers
• The time and date are correct on both phone and windows 10

I have NO clue what to do anymore. I can't get passed it. Can someone please advice. (see screenshots)

Dear,

i opened my firefox and found my self logged out automaticly

and when am trying to login and enter the activation code sent to my email i recieve this msg

You’ve tried too many times. Please try again ⁨in 5 minutes⁩.

Hi everyone,

I looked on multiple forums but can't find an answer.

I am trying to setup 2 way authentication for the Mozilla extensions account. But i can't get past the "Confirm backup authentication code" part.

I get the error:

"There was a problem confirming your backup authentication code"

Here is the codes that i got (can be public because it's expired and i left 2 of them out):

w1bycwwp6w eym2bx8yaj wh5h7c77qv s3snv0ez0x 9aveb72jw1 x8d3rzedah

So i copy just one of them, and i get the error.

• No im not copying all of them, just one
• No i don't have spaces in there
• No there is no capitals or anything in there or caps (im copy pasting).

It's very odd and i can't upload my application.

Please advice. Anyone have some idea?

Thank you in advance!

I am having trouble signing into my account ******@gmail.com. I no longer have an authenticator app account and I used all of my backup codes. I do have a recovery key though. I hope this helps in recovering access to my account.

I received an email at an email account I don't use for my Mozilla Firefox, thus why seems suspicious and strange to me. So I researched it here and saw the answer to another persons same question. I did go and check, I am logged in. Firefox is my primary and I use it constantly. Also on my phone and tablet, same account. As I write this, I have about 15 tabs open and active. The email associated to my account is not the same as the one I got this email at. The email I got it in, I use for solicitation, signing up for things and things I don't trust. This is what the email stated (same info as what was posted by the other person that got this same post) I copied and paste vs. Screen shot... so the Mozilla logo didn't show up. MIND YOU, I HAVE NEVER GONE 2 YEARS WITH NOT BEEN ACTIVE ON FIREFOX. AND I ONLY HAVE ONE ACCOUNT. PLEASE ADVISE --- The email they sent it to is [email removed]@gmail.com
