Microsoft Entra ID explained
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 single sign-on experience, regardless of whether their applications are cloud-based or on-premises.
Entra ID offers many 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.[2]
On July 11, 2023, Microsoft announced the renaming of Azure AD to Microsoft Entra ID to improve consistency with other Microsoft cloud products.[3] The name change took place on July 15, 2023.[4]
