Microsoft identity platform (v2.0) overview

Microsoft identity platform is an evolution of the Azure Active Directory (Azure AD) developer platform. It allows developers to build applications that sign in all Microsoft identities and get tokens to call Microsoft APIs, such as Microsoft Graph, or APIs that developers have built. The Microsoft identity platform consists of:

  • OAuth 2.0 and OpenID Connect standard-compliant authentication service that enables developers to authenticate any Microsoft identity, including:
    • Work or school accounts (provisioned through Azure AD)
    • Personal Microsoft accounts (such as Skype, Xbox, and
    • Social or local accounts (via Azure AD B2C)
  • Open-source libraries: Microsoft Authentication Libraries (MSAL) and support for other standards-compliant libraries
  • Application management portal: A registration and configuration experience built in the Azure portal, along with all your other Azure management capabilities.
  • Application configuration API and PowerShell: which allows programmatic configuration of your applications through the Microsoft Graph API and PowerShell, so you can automate your DevOps tasks.
  • Developer content: conceptual and reference documentation, quickstart samples, code samples, tutorials, and how-to guides.

For developers, Microsoft identity platform offers seamless integration into innovations in the identity and security space, such as passwordless authentication, step-up authentication, and Conditional Access. You don’t need to implement such functionality yourself: applications integrated with the Microsoft identity platform natively take advantage of such innovations.

With Microsoft identity platform, you can write code once and reach any user. You can build an app once and have it work across many platforms, or build an app that functions as a client as well as a resource application (API).

Getting started
