Through these security requirements users in a partner tenant will be required to authenticate using MFA when accessing Microsoft commercial cloud services. Third-party solutions can be used to fulfill these requirements. Microsoft no longer provides validation testing to independent identity providers for compatibility with Azure Active Directory. To test your product for interoperability, see Azure AD Identity Provider Compatibility Docs.
Important
When you're using a third-party solution, it's important to verify that the solution is issuing the authentication method reference (AMR) claim that includes the MFA value. See Testing the Partner Security Requirements for details on how validating your third-party solution is issuing the expected claim.
