I’m not sure I quite understand how this would make them unable to support normal 2fa until now.

Keycloak is one of the most configurable and flexible auth solutions, and there is no way it didn’t support otp based 2fa until recently.

Well fucking finally. I have no idea what took them so long.

Is the same checkbox in the settings that Firefox has, it’s just on by default. Have you considered just turning it off?

Seems like a much simpler solution is to just use LibreWolf where all these things are removed from the program already for you. That’s the point of the fork.
