Introduction
Identity is the foundation of cloud security.
Almost every Azure service integrates with Microsoft Entra ID (formerly Azure Active Directory) for authentication and authorization.
Azure Identity is one of the most frequently asked interview topics because every production application requires secure authentication and access control.

Microsoft Entra ID (formerly Azure Active Directory) is Microsoft's cloud-based identity and access management service.
2. Why use Microsoft Entra ID?
- Authentication
- Authorization
- Single Sign-On
- MFA
