Thank you for your replay,
I tried to use the custom account provider as suggested but i still stuck with the OTP input, how can I edit Dundas login page to accept the OTP from the user or how can I generate another page to take the OTP from the user after I ensure that the entered user name and password are correct.
Also, I have found another solution in Dundas called Custom Login URL which i can provide external page to authenticate the user, but how I can use it or how I can redirect back to Dundas after authenticate the user in the custom page.
the web resources is very limited and I can’t find any details information.
We are showing sensitive information in Dundas BI and we have notice period from our security team to enable Two Factor Authentication or the tool will be blocked by them.
Your help is much appreciated.
