Overview of Azure Multi-Factor Authentication for your organization

There are multiple ways to enable Azure Multi-Factor Authentication for your Azure Active Directory (AD) users based on the licenses that your organization owns.

Investigate signals and enforce MFA if needed

Based on our studies, your account is more than 99.9% less likely to be compromised if you use multi-factor authentication (MFA).

So how does your organization turn on MFA even for free, before becoming a statistic?

Free option

Customers who are utilizing the free benefits of Azure AD can use security defaults to enable multi-factor authentication in their environment.

Office 365 Business Premium, E3, or E5

For customers with Office 365, there are two options:

  • Azure Multi-Factor Authentication is either enabled or disabled for all users, for all sign-in events. There is no ability to only enable multi-factor authentication for a subset of users, or only under certain scenarios. Management is through the Office 365 portal.
  • For an improved user experience, upgrade to Azure AD Premium P1 or P2 and use Conditional Access. For more information, see secure Office 365 resources with multi-factor authentication.

Azure AD Premium P1

For customers with Azure AD Premium P1 or similar licenses that include this functionality such as Enterprise Mobility + Security E3, Microsoft 365 F1, or Microsoft 365 E3:

Use Azure AD Conditional Access to prompt users for multi-factor authentication during certain scenarios or events to fit your business requirements.

Azure AD Premium P2

For customers with Azure AD Premium P2 or similar licenses that include this functionality such as Enterprise Mobility + Security E5 or Microsoft 365 E5:

Provides the strongest security position and improved user experience. Adds risk-based Conditional Access to the Azure AD Premium P1 features that adapts to user's patterns and minimizes multi-factor authentication prompts.
