Azure Active Directory for developers
Microsoft Entra ID is a cloud identity service that allows developers to build apps that sign in users with a Microsoft work or school account. Microsoft Entra ID supports building single-tenant line-of-business (LOB) apps as well as multi-tenant apps. IMPORTANT: This content is for the older Azure AD v1.0 endpoint, use the Microsoft identity platform (https://aka.ms/identityplatform) for new projects.
