Microsoft Entra ID is used by IT admins to control access to corporate apps and resources, based on business requirements. For example, Microsoft Entra ID can also be set up to require multi-factor authentication when accessing important organizational resources. It provides powerful tools to automatically help protect user identities and credentials and to meet an organization’s access governance requirements.

Developers use Microsoft Entra ID as a standards-based approach for adding single sign-on (SSO) to their apps, so that users can sign in with their pre-existing credentials. Microsoft Entra ID also provides application programming interfaces (APIs) that allow developers to build personalized app experiences using existing organizational data.

Subscribers to Azure services, Microsoft 365, or Dynamics 365 automatically have access to Microsoft Entra ID. Users of these services can take advantage of included services and can also enhance their Microsoft Entra implementation by upgrading to premium licenses.
