Azure Active Directory

Introduction

Azure Active Directory (Azure AD) is a cloud-based identity and access management service from Microsoft. It provides services such as user authentication, single sign-on (SSO), and application management. Azure AD enables organizations to manage users and groups, and to secure access to applications and resources.

Key Points

Azure AD is not a traditional directory service; it is designed for the cloud.
It supports various authentication protocols including OAuth, OpenID Connect, and SAML.
Azure AD can integrate with on-premises directories through Azure AD Connect.
It provides multi-factor authentication (MFA) for enhanced security.
