1.2.5 Require Multi-factor Authentication for Risky Sign-ins (Manual)

Profile Applicability

• Level 1


For designated users, they must use their Multi-Factor Authentication (MFA) process on login.


Enabling multi-factor authentication is a recommended setting to limit the potential of accounts being compromised and limiting access to authenticated personnel.


There is an increased cost, as Conditional Access policies require Azure AD Premium. Similarly, they may require additional overhead to maintain if users lose access to their MFA.

Additional Information

Test these policies by using the What If tool in the References. Setting these can create issues with logging in for users until they use an MFA device linked to their accounts. You can perform further testing via the insights and reporting resource the in References which monitors Azure sign ins.
