What is Azure AD ?

Microsoft Azure Active Directory (Azure AD) is a cloud-based identity and access management solution. Its primary purpose is to provide authentication and authorization when accessing cloud-based resources. However, you can also leverage its functionality to protect on-premises applications. In both cases, you can further streamline and enhance secure access to sensitive services and data by taking advantage of Azure AD’s single sign-on (SSO), federation, and Microsoft Azure Multi-Factor Authentication capabilities.
