Question

There are many scenarios where there is Azure ad b2c is main authentication provider and there are additional authentication provider configured to work with it. for eg Google, Facebook, etc. I have configured login with Google and Login with Facebook with Azure AD b2c. But in this case I need to add button like Login with B2c.

I have asp.net core website already configured with one OpenId based authentication provider (for eg let's say Salesforce) Now I want to configure additional authentication provider that is Azure AD B2c. What configuration do I need to do b2c side and how to add additional authentication provider asp.net core web application side?

Answer 1

Yes, you can use Third-party identity verification and proofing .

Azure's ISV partner network extends it's solution capabilities to help you build seamless end-user experiences. With Azure AD B2C, you can integrate with ISV partners to enable multi-factor authentication methods, enable Secure Customer Authentication (SCA), perform Role-Based Access Control, and combat fraud through identity verification and proofing.

Answer 2

I'm no expert on Azure AD specifics, but there is an industry standard for Open Id Connect federation.

The key goal is to integrate external providers with no extra cost to your apps. My blog post explains the architecture.

So while this may not be a complete answer, I hope it helps you to clarify what you want. It is easy to get lost in vendor specific marketing articles if not careful.
