2FA on community.mp3tag.de

Somehow the 2FA Authentication page on https://community.mp3tag.de is malformed.

The field for the code is recognised by the authenticator app as the “email / username” and not as the 2FA code field.

This prohibits automatic filling the code by the app

This is probably happening on all communities running Discourse for you.

I've just checked and it uses the correct role autocomplete="one-time-code", but it looks like some authenticator apps have problems with the input separated into multiple fields.

It's outside of my area of influence, but you can report it as an issue to the Discourse community (providing a little more information regarding OS, Browser, and authenticator app).

Thanks for the reply.

I investigated a bit further as you confirmed the correct role is used.

When I login from Vivaldi (Chromium) + Authenticator-Addon + Authenticator-App everything works as desired

When I use Firefox 140.7.esr + Authtenticator-Addon + Same Authenticator-App, the Username is used for 2FA.

As it works in Vivaldi, I’m assuming now, that it is :

  • either Discourse providing another role when Firefox is the browser
  • or there is a problem with the Authenticator-Addon for Firefox (which is weird as 2FA works in Firefox for other sites!)
