Microsoft Entra ID
Microsoft Entra ID (formerly 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 like Microsoft 365, Dynamics 365, Azure, and cloud-based applications. 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. On July 11, 2023, Microsoft announced the renaming of Azure AD to Microsoft Entra ID to improve consistency with other Microsoft cloud products. This decision received a largely negative response from the security community. The name change took place on July 15, 2023. Service Limits and Restrictions
