Microsoft identity platform allows developers to build applications that sign in all Microsoft identities and get tokens to call Microsoft APIs like Microsoft Graph, or APIs you've built. This full-featured platform consists of an OAuth 2.0 and OpenID Connect standard-compliant authentication service, open-source libraries, application registration and configuration, robust conceptual and reference documentation, quickstarts, code samples, tutorials, and how-to guides.
