How To: Configure the Azure AD multifactor authentication registration policy

Azure Active Directory (Azure AD) Identity Protection helps you manage the roll-out of Azure AD multifactor authentication (MFA) registration by configuring a Conditional Access policy to require MFA registration no matter what modern authentication app you're signing in to.

What is the Azure AD multifactor authentication registration policy?

Azure AD multifactor 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 AD multifactor authentication.

We recommend that you require Azure AD multifactor authentication for user sign-ins because it:

  • Delivers strong authentication through a range of verification options.
  • Plays a key role in preparing your organization to self-remediate from risk detections in Identity Protection.

User experience

Azure AD Identity Protection will prompt your users to register the next time they sign in interactively and they'll have 14 days to complete registration. During this 14-day period, they can bypass registration if MFA isn't required as a condition, but at the end of the period they'll be required to register before they can complete the sign-in process.
