How To: Configure the Azure Multi-Factor Authentication registration policy

Azure AD Identity Protection helps you manage the roll-out of multi-factor authentication (MFA) registration by configuring a Conditional Access policy to require MFA registration no matter what modern authentication app you are signing in to. This article explains what the policy can be used for and how to configure it.

What is the Azure Multi-Factor Authentication registration policy?

Azure Multi-Factor Authentication provides a means to verify who you are using more than just a username and password. It provides a second layer of security to user sign-ins. In order for users to be able to respond to MFA prompts, they must first register for Azure Multi-Factor Authentication.

We recommend that you require Azure Multi-Factor Authentication for user sign-ins because it:

  • Delivers strong authentication with a range of easy verification options
  • Plays a key role in preparing your organization to protect and recover from risk detections in Identity Protection

How do I access the registration policy?

The MFA registration policy is in the Configure section on the Azure AD Identity Protection page.
