Microsoft Entra ID is a cloud-based identity and access management service that enables employees to access both external resources, such as Microsoft 365 and the Azure portal, and internal resources, including corporate intranet apps and custom cloud applications developed for the organization.

For IT admins, Microsoft Entra ID allows control over app access based on business needs, supports multifactor authentication, and automates user provisioning. App developers can leverage it as a standards-based authentication provider to implement single sign-on (SSO) and create personalized experiences using organizational data.

Microsoft Entra ID offers a Free tier that includes user and group management, basic reports, and single sign-on capabilities. The P1 license adds features for hybrid users and advanced administration, while the P2 license includes risk-based Conditional Access and Privileged Identity Management, enhancing security and governance.
