Can you share pictures of what you did. I appreciate the links, but I need to see what you did. Also, is this for a business that has 2FA enabled for the company, and also is it enabled for Anonymous (Probably not).
Are people "authenticated" and things load, but doesn't force them to do 2FA or is it not worknig at all?
Also, note, if you are working with people who already have authenticated for the company with 2FA and they are simply hitting a site internally, they won't necessarily get asked for it again, so make sure to please test in private or incognito mode :-)
Cheers!!
