Hello Toufiq.
As mentioned, I am opening this thread to follow up with the other one about W3C Authentication to share some sensitive data with you.
In the video you shared you showed the activation of MfA via back end, but our users will not have access to the back end, they will only be able to update their account / profiles via front end.
When I set the template to Helix Ultimate, it only shows the Passkey option when I change the template to Cassiopeia, then the MfA is accessible and can be activated.
So, my problem is not on the login form, it is on the Edit Profile page that is not loading correctly on Helix Ultimate.
In the Hidden Content is the link of the screen capture I made to show you.
Thanks,
Diego
