# OpenIddict: the OpenID Connect stack you'll be addicted to

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**.

OpenIddict fully supports the **[code/implicit/hybrid flows](https://openid.net/specs/openid-connect-core-1_0.html)**, the **[client credentials/resource owner password grants](https://tools.ietf.org/html/rfc6749)** and the [device authorization flow](https://tools.ietf.org/html/rfc8628). You can also create your own custom grant types.

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, but you can also provide your own stores.
