1m 8s

In this lesson, I’ll start with the purpose of Azure AD, with a focus on user authentication. Then I’ll cover some of the ways you can make your authentication more robust, including multi-factor authentication and conditional access. Next, I’ll go over some Azure AD services that can help you increase your security and expand your access, including Identity Protection, Privileged Identity Management, and External Identities. Finally, I’ll explain how you can use Azure AD Domain Services to support legacy authentication methods.
