MFA license on ADFS applications

I have been trying to clarify about MFA license requirement for applications (both SAAS and on-premise) federated in ADFS. We use Azure MFA in our ADFS farm. Based on the link below, MFA for on-premise applications does require either P1 and P2 license. MFA works fine in ADFS even if we didn't assign a P1 license to the user for those applications. So my question is if P1 is needed but Azure just doesn't check it or it is not a requirement unless users are authenticate through application proxy in Azure AD.

Thank you.

    Hi @HK G • Thank you for reaching out.

    Yes, MFA for on-premise applications does require either P1 or P2 license, but this requirement is not hard enforced. Which means, when P1/P2 license is assigned even to a single user account in a given tenant, the P1/P2 capabilities are unlocked for that tenant and all users in that tenant can use P1/P2 features. However, to stay compliant, all the users who are using the features that require P1/P2 license must be assigned with these licenses.

    So, MFA for a user without either P1 or P2 license can be enabled, but in that case you will be non-compliant.
