Microsoft Entra ID
Cloud-based identity management service
From Wikipedia, the free encyclopedia
Microsoft Entra ID (formerly known as Microsoft Azure Active Directory or Azure AD) is a cloud-based identity and access management (IAM) solution. It is a directory and identity management service that operates in the cloud and offers authentication and authorization services to various Microsoft services, such as Microsoft 365, Dynamics 365, Microsoft Azure, and third-party services.[1] Entra ID provides users with a single sign-on experience, called "work or school accounts",[2] regardless of whether their applications are cloud-based or on-premises.

Entra ID offers various authentication methods, including password-based, multi-factor, smart card, and certificate-based authentication. It also includes several security features, such as conditional access policies, risk-based authentication, and identity protection.[3]
On July 11, 2023, Microsoft announced the renaming of Azure AD to Microsoft Entra ID to improve consistency with other Microsoft cloud products.[4] The name change took place on July 15, 2023.[5]
Security
On July 14, 2025, a security vulnerability allowing a user to gain administrator privileges to every Entra ID directory was discovered. A fix was issued on July 17, 2025.[6]
