OpenIddict

The OpenID Connect stack you'll be addicted to.

What is OpenIddict?

OpenIddict aims at providing a versatile solution to implement OpenID Connect client, server and token validation support in .NET applications.

[!TIP] While the client, server and token validation features can be used in any ASP.NET 4.6.2+ or ASP.NET Core 2.3+ web application, the client feature can also be used in Android, iOS, Linux, Mac Catalyst, macOS and Windows applications to integrate with OpenIddict-based identity providers or any other OAuth 2.0/OpenID Connect-compliant implementation.

OpenIddict fully supports the code/implicit/hybrid flows, the client credentials/resource owner password grants, the device authorization flow and the token exchange grant.

OpenIddict natively supports Entity Framework Core, Entity Framework 6 and MongoDB out-of-the-box and custom stores can be implemented to support other providers.

Getting started

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.

Developers looking for a simple and turnkey solution are strongly encouraged to evaluate Volo.OpenIddict.Pro, which is based on OpenIddict, supports all the common OAuth 2.0/OpenID Connect flows and offers a powerful applications/scopes management GUI.

[!TIP] Looking to integrate with a SAML2P Identity Provider (IDP) or Service Provider (SP)? Rock Solid Knowledge, a sponsor of OpenIddict, is developing a range of identity components to enhance your OpenIddict solution. The first of these is their popular SAML2P component.

Certification

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.

[!TIP] 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).

Security policy

Security issues and bugs should be reported privately by emailing [email protected]. You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message.

Support policy

If you need support, please first make sure you're sponsoring the project or are a regular contributor: GitHub tickets opened by users who haven't contributed to the project or don't actively sponsor it will be automatically closed.

[!TIP] Depending on the tier you selected, you can open a GitHub ticket or send an email to [email protected] for private support.

Alternatively, you can also post your question on Gitter.

Support is only offered for the latest stable version of OpenIddict. There are, however, two exceptions to this policy:

• ABP Framework users receive patches for OpenIddict for as long as ABP Framework itself is supported by Volosoft (typically a year following the release of a major ABP version), whether they have a commercial ABP license or just use the free packages:

• OpenIddict sponsors are offered extended support depending on the selected sponsorship tier:
  • Tier 6 sponsors get full support for the previous version 1 month following the release of a new major version.
  • Tier 7 sponsors get full support for the previous version 6 months following the release of a new major version.
  • Tier 8 sponsors get full support for the previous version 12 months following the release of a new major version.
  • Tier 9 sponsors get full support for the previous version 24 months following the release of a new major version.

[!TIP] For more information on the different tiers and the benefits they offer, visit GitHub Sponsors.
