Unable to generate backup codes for Two Factor authentication here on NodeBB



  • I enabled two factor authentication here on community.nodebb.org. The association to my 2FA app works fine but I am unable to create backup codes. I tried with Authy, FreeOTP and Google Authenticator.

    Is this a known bug with the current NodeBB and Two-Factor plugin?



  • I have re-tested this and do believe there is a problem with the current version of NodeBB and the 2FA plugin.

    Here on community.nodebb.org I am unable to generate backup 2FA codes. When I test this on my v1.0.2 NodeBB forum I am able to create 2FA codes. It seems that the problem is not dependent upon which 2FA app I use.

    Would someone else who is using two factor authentication on this site please generate (or re-generate) their backup codes and see if after pressing the button to have them created they actually display on the screen. For me I press the button, my notification bell alerts but no codes are displayed to be copied.

    Thank you.

    I can confirm. I tried generating codes for this community and got an alert, but no codes were shown and the notification just links to the homepage. I also tried on the v1.1.2 (SHA fdd85140587799a442edb9f3ca1b8ecaf4ea0bb9) and I wouldn't even get a notification @julian

    Hey guys, this should actually be resolved, but just not updated on this forum. Can you try on your own dev?

    Seems to be working again! What was the issue?

    Just a breaking change in NodeBB core, it looks like :smile:

    @julian Not sure if related, but 2FA isn't working again for whatever version community.nodebb is running right now, I just tried to disable 2FA and nothing happens (Trying to port over my codes to a new device)
