OpenIddict aims at providing a versatile solution to implement OpenID Connect client, server, and token validation support in .NET applications. It offers comprehensive support for various OAuth 2.0/OpenID Connect flows, including code, implicit, hybrid, client credentials, device authorization, and token exchange. The core strength of OpenIddict lies in its flexibility and extensibility, allowing developers to customize its behavior and integrate it with other systems.
OpenIddict is notable for its support of multiple database providers (EF Core, EF 6, MongoDB, and custom stores). It offers a flexible architecture suitable for various application types, including web applications, native mobile apps, and even systems without a traditional UI. The project emphasizes developer control through a framework-based approach, encouraging custom implementation for enhanced integration and security. The readily available sample repository allows users to easily get started with core flows.
