OpenIddict aims at providing a versatile solution to implement an OpenID Connect server and token validation in any ASP.NET Core 2.1 (and higher) application. ASP.NET 4.6.1 (and higher) applications are also fully supported thanks to a native Microsoft.Owin 4.2 integration.
Developers looking for a simple and turnkey solution are strongly encouraged to use OrchardCore and its OpenID module, which is based on OpenIddict, comes with sensible defaults and offers a built-in management GUI to easily register OpenID client applications.
To implement a custom OpenID Connect server using OpenIddict, read Getting started.
Samples demonstrating how to use OpenIddict with the different OAuth 2.0/OpenID Connect flows can be found in the dedicated repository.

❗ Note: ASP.NET Core 2.1 on .NET Core 2.1 is no longer supported. While OpenIddict 4.x can still be used on .NET Core 2.1 thanks to its .NET Standard 2.0 compatibility, users are strongly encouraged to migrate to ASP.NET Core/.NET 6.0. ASP.NET Core 2.1 on .NET Framework 4.6.1 (and higher) is still fully supported.
ℹ️ Note: the following features are not available when targeting .NET Framework 4.6.1:
- X.509 development encryption/signing certificates: calling
AddDevelopmentSigningCertificate()will result in a
PlatformNotSupportedExceptionbeing thrown at runtime if no valid development certificate can be found and a new one must be generated.
- X.509 ECDSA signing certificates/keys: calling
AddSigningKey()with an ECDSA certificate/key will always result in a
PlatformNotSupportedExceptionbeing thrown at runtime.
Unlike many other identity providers, OpenIddict is not a turnkey solution but a framework that requires writing custom code to be operational (typically, at least an authorization controller), making it a poor candidate for the certification program.
While a reference implementation could be submitted as-is, this wouldn't guarantee that implementations deployed by OpenIddict users would be standard-compliant.
Instead, developers are encouraged to execute the conformance tests against their own deployment once they've implemented their own logic.
The samples repository contains a dedicated sample specially designed to be used with the OpenID Connect Provider Certification tool and demonstrate that OpenIddict can be easily used in a certified implementation. To allow executing the certification tests as fast as possible, that sample doesn't include any membership or consent feature (two hardcoded identities are proposed for tests that require switching between identities).
