How to retrieve Authentication Method Reference (amr claim) from IDP using B2C custom policy?

Question

I am using SAML authentication to connect to Azure Entra ID from Azure B2C with a custom policy. I receive authnmethodsreferences as an output from Entra, but I'm unable to obtain it in the ID token I receive from B2C.

Can someone please guide me on how to retrieve this additional claim from the B2C token?

Hi Aditya Gour (NAV India) •

Azure AD B2C doesn’t issue an amr claim like Azure AD does. You need to output this claim at the relevant technical profiles based on your orchestration step and then in the relying party section using a custom policy to get this claim in ID token.

Hope this will help.

Thanks,
