Which sign-in protocol to use?

Hi, we are an ISV with an app that uses ASP.NET forms authentication with our own db of users/pwd. One of our clients uses Active Directory and Okta in their corp and we want to enable authentication via Okta for that subset of users.

For this scenario can we use openidconnect with okta along the lines of - https://developer.okta.com/blog/2018/08/29/secure-webforms-with-openidconnect-okta.

Or do we have to use SAML (or perhaps WS-Fed)?


Hi, any pointers on this will be really appreciated. Thx.
