Features and licenses for Microsoft Entra multifactor authentication

  • บทความ

To protect user accounts in your organization, multifactor authentication should be used. This feature is especially important for accounts that have privileged access to resources. Basic multifactor authentication features are available to Microsoft 365 and Microsoft Entra ID users and administrators for no extra cost. If you want to upgrade the features for your admins or extend multifactor authentication to the rest of your users with more authentication methods and greater control, you can enable Microsoft Entra multifactor authentication by using Conditional Access. For more information, see Common Conditional Access policy: Require MFA for all users.

Important

This article details the different ways that Microsoft Entra multifactor authentication can be licensed and used. For specific details about pricing and billing, see the Microsoft Entra pricing page.

Available versions of Microsoft Entra multifactor authentication

Microsoft Entra multifactor authentication can be used, and licensed, in a few different ways depending on your organization's needs. All tenants are entitled to basic multifactor authentication features by using security defaults. You may already be entitled to use advanced Microsoft Entra multifactor authentication depending on the license you currently have. For example, the first 50,000 monthly active users in Microsoft Entra External ID can use MFA and other Premium P1 or P2 features for free. For more information, see Azure Active Directory B2C pricing.

The following table details the different ways to get Microsoft Entra multifactor authentication and some of the features and use cases for each.

Feature comparison based on licenses

The following table provides a list of the features that are available in the various versions of Microsoft Entra ID for multifactor authentication. Plan out your needs for securing user authentication, then determine which approach meets those requirements. For example, although Microsoft Entra ID Free provides security defaults that provide Microsoft Entra multifactor authentication where only the mobile authenticator app can be used for the authentication prompt. This approach may be a limitation if you can't ensure the mobile authentication app is installed on a user's personal device. See Microsoft Entra ID Free tier later in this topic for more details.
