Making two Enterprise Apps share the same certificate

Hi all, I have a request from a vendor to create a second enterprise application to facilitate SSO into their application - one for desktop users to login with and one for users coming from the mobile app.

The only difference between these two applications will be the ACS URL, everything else needs to be the same... even the certs. (Entity ID will be slightly different as well)

I know that one app can have multiple ACS URLs, but for this vendor in order for them to process that we would have to switch from our current IDP-initiated setup to an SP-initiated setup, which our business does not want to do at this time.

So, my question today is: Is there a way to create two enterprise apps in Azure with the same certificate? Can I simply export the certificate out of one app and import it to the other, or are there more steps that I have to take?

Thanks!

Hi @TaylorODell-2661 · Thank you for reaching out.

Yes, you can use same certificate in multiple Enterprise applications, provided that you are using a certificate issued by an external CA and not generated by Azure AD.

The reason is, if the certificate is generated by Azure AD, you will not get access to the Private key and you can export only the Public key. However when Importing a certificate in SSO settings of Enterprise App, you will need to upload PFX file, which includes Private key as well.
