OpenID Connect Provider and OAuth 2.0 Authorization Server Framework based on ASP.NET Core

IdentityServer4 is an OpenID Connect Provider and OAuth 2.0 Authorization Server Framework built on ASP.NET Core.

Allows for the implementation of single sign-on and access control for modern web applications and APIs using protocols such as OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

IdentityServer4 is officially certified by the OpenID Foundation and thus spec-compliant and interoperable. It is part of the .NET Foundation, and operates under their code of conduct. It is licensed under Apache 2 (an OSI approved license).

For the .NET 4.x, katana based version see Identity Server 3
