Setting up Azure Multi-Factor Authentication (MFA) is a crucial step in securing your Azure Active Directory (Azure AD) and protecting your organization's sensitive data.

To get started, you'll need to register for an Azure AD account if you haven't already. This will give you access to the Azure portal, where you can manage your Azure AD settings.

First, navigate to the Azure portal and sign in with your Azure AD account. Once you're in, click on the "Azure Active Directory" tab in the left-hand menu.

From there, click on "Security" and then select "Conditional Access" to set up policies for your users.

Before You Begin

Before you begin setting up Azure MFA, there are a few things to keep in mind. You'll need to be a Global admin to manage MFA.

To ensure a smooth setup process, you should first turn off legacy per-user MFA if it's currently enabled.

If you have third-party directory services with Active Directory Federation Services (AD FS), you'll need to set up the Azure MFA Server for advanced scenarios.

Here are some advanced configuration options to consider:

Remembered Devices and Certificates

Remembered Devices and Certificates is a powerful feature that can simplify the authentication process for your users.

Each Entra ID CA custom control is a single application in Duo, even though you may opt to apply that single control to multiple Entra ID or Office applications.

If you enable Remembered Devices on the Microsoft Azure Active Directory Duo application, then if a user signs into one application that has that control applied and chooses to remember that device when performing Duo authentication, they won't need to perform Duo MFA again for other Entra ID and Office applications with that same Duo control applied.

You can create multiple Duo custom controls with different settings if you want the Entra ID and Office applications you protect with Duo to have distinct Remembered Devices settings, or any other combination of Duo settings.

Active Directory
