Primary and secondary authentication mechanisms are working well with my ADFS environment. The problem is the 2FA prompt iframe is a bit small which forces a vertical scroll. This causes users to not see buttons and other important content that's only
visible by scrolling down. The 2FA vendor has suggested that there is a "customAuthArea" that could be modified within a new theme of ADFS. I already have a custom theme with illustration, logo, and some onload.js modifications, but I do not know
where this can be found.
