Can't setup 2FA - won't accept backup code

[jbirnick]

Description

I just created a Mozilla Account to publish my add-on. For publishing my add-on, I need to setup 2FA. However, after confirming a 2FA code, it would ask me to confirm with a backup code. And then no matter what backup code from the previous page I give them, it would always just say "there was a problem confirming your backup authentication code".

I found another user on reddit who had the same problem a month ago: https://www.reddit.com/r/firefox/comments/1f8g4pb/cant_add_2fa_to_mozilla_account/

Steps to reproduce

Create a new Mozilla account and try to setup 2FA.

Environment

Arch Linux. Tried with both Firefox and Chromium.

i have the exact same issue. copy pasted from the codes, but at step 3, nothing works. had to wait 15 minutes, then tried again with authy, code gets generated, enter the authy code, everything is fine.. then we get to the backup code, copy directly from the window that asks you to download and backup this file.. then add one of the code into step 3, fail

[jbirnick]

Yeah same.

[ReneDussault]

Yeah same.

it JUST allowed me to make it happen. im not sure why, but now it works... idk, weird bug

99% of the time issues like these are that a clock on one of the devices is off. Even a few seconds can matter. Would you verify that your devices clocks are accurate and sync'd to a timeserver?

[jbirnick]

I don't think it was related to that; it also worked for me when it worked for ReneDussault.

Also, for the backup codes it should not be related to any timing, right? Again, providing the 6-digit authentication code did work, but providing the backup code (which is not timing-based) did not work.

[clouserw]

Right. Timing only matters for the 2FA codes

Looks like #17799 might be related also

[jbirnick]

Yeah that's the same thing.

I got the same thing, try to setup, won't accept recovery codes for some reason

[prefabcode]

I have a temp fix for this issue. I signed up for an account via one of the two options (google / apple). The reason why it doesn't accept recovery code is because if you sign up via google / apple, you do not have a password set on your account.

Go here: https://accounts.firefox.com/settings/
Set up a password for your account, and then you will be able to set 2FA. You can setup 2FA right from that settings page.

[jbirnick]

Well but I did not sign up with Google/Apple, so I had a password, and it still didn't work.

Hello 👋🏽, a fix for this has landed in #17893. Thanks again for the report!

[Noxor11]

I see this fix is already merged and I'm not sure if the changes are up already, but I still had the same error several times just now. I'm still not able to confirm the backup authentication code.

Hey Noxor, I'll see if this can be uplifted but otherwise we expect the next production release to be Nov 13.
