# 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](https://documentation.openiddict.com/integrations/aspnet-core),
> the client feature can also be used in
> [Android, iOS, Linux, Mac Catalyst, macOS and Windows applications](https://documentation.openiddict.com/integrations/operating-systems)
> 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](http://openid.net/specs/openid-connect-core-1_0.html)**,
the **[client credentials/resource owner password grants](https://datatracker.ietf.org/doc/html/rfc6749)**,
the [device authorization flow](https://datatracker.ietf.org/doc/html/rfc8628) and the **[token exchange grant](https://datatracker.ietf.org/doc/html/rfc8693)**.
OpenIddict natively supports **[Entity Framework Core](https://www.nuget.org/packages/OpenIddict.EntityFrameworkCore)**,
**[Entity Framework 6](https://www.nuget.org/packages/OpenIddict.EntityFramework)** and **[MongoDB](https://www.nuget.org/packages/OpenIddict.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](https://documentation.openiddict.com/guides/getting-started/)**.
**Samples demonstrating how to use OpenIddict with the different OAuth 2.0/OpenID Connect flows**
can be found in the [dedicated repository](https://github.com/openiddict/openiddict-samples).
**Developers looking for a simple and turnkey solution are strongly encouraged to evaluate [Volo.OpenIddict.Pro](https://abp.io/modules/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](https://www.openiddictcomponents.com/?utm_source=openiddictgithubmain&utm_campaign=openiddict).
--------------
## 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](https://github.com/openiddict/openiddict-samples/tree/dev/samples/Contruum/Contruum.Server) 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).
