How to Replace primary authentication with custom authentication in ADFS

Question

We have a Setup windows R2 2012 server with ADFS enabled and able to add MFS successfully, Now I would like to promote this as a Primary authenticator.

I know that from ADFS 2019 we can override the primary authenticator, but how it can be achieved in the older version ?

Is there any other possibilities like integrate ADFS with any SAML provider. If so, where will be the authentication takes place ?

Answer 1

This is not possible on 2012. 2016 allows you to add Azure MFA as a primary authenticator and 2019 allows you to add custom authenticators as primary. See here and here.
