Authenticate Entra ID users with External ID External Tenant CIAM

Question

We are looking at External ID external tenants as a possible CIAM solution rather than B2C which appears to be end of life / sunsetting now.

However, I can't seem to find out if it is currently possible to have a sign up / sign in flow that supports Entra ID? This is obviously possible in B2C via a custom flow, and seems like it would be a fairly common requirement for SaaS apps aimed at business / enterprise customers.

If it isn't currently available, will it ever be? if so, when?

Hi @Matthew Gribben

Thank you for posting this in Microsoft Q&A.

I understand you are looking for whether it's possible to have a sign-up/sign-in flow that supports Entra ID in External ID External Tenant CIAM.

Currently, the Microsoft Entra ID sign-up option is unavailable. However, our product team is continuously evolving and actively working on integrating the Microsoft Entra option in Microsoft Entra External ID soon. Although we don't have a specific timeline for its release,

I recommend keeping an eye on the monthly updates at https://learn.microsoft.com/en-us/entra/external-id/customers/whats-new-docs for the latest information on external tenants.

Hope this helps. Do let us know if you any further queries.

Thanks,

Navya.
