Auth0 as the Social Login When Using Azure Entra as the IDP

[matthew.hartz]

Ready to post? First, try searching for your answer.
Hi,

I’ve seen some posts on how to do the inverse, where you could go open the auth0 lock and see your Azure Entra account as a social login.

What my goal is I have a Service Provider that uses Azure Entra as it’s IDP but I want to authenticate users who use my other application’s auth0 tenant as the IDP.

First is this possible, and second is there documentation that I am not finding that goes over how to do such a case?

Thank you!

Hi @matthew.hartz,

Yes it is possible to use Auth0 as the Identity Provider and Azure Entra as the Service Provider. I have found some documentation about this. I hope it will help.

Auth0 act as an Identity Provider to Azure AD

Problem statement We need to make Auth0 the source for users. In other words, Auth0 is the IdP and Azure AD is the SP/relying party. Can Auth0 act as an Identity Provider to Azure AD? Solution You can implement this as below: In the Azure AD portal, go to External Identities in the left sidebar → All identity providers → New SAML/WS-Fed IdP. In Auth0, this would be a generic SAML setup using the SAML2 Web App addon. Reference

If you have any other questions feel free to ask.

Have a good one,
Vlad
