Duende Software sponsors a series of free open source libraries under the Apache 2 license.
These libraries help with building OAuth 2.0 and OpenID Connect clients.
A set of .NET libraries that manage OAuth and OpenId Connect access tokens. These tools automatically acquire new tokens when old tokens are about to expire, provide conveniences for using the current token with HTTP clients, and can revoke tokens that are no longer needed.
The latest version of Duende.AccessTokenManagement targets .NET 8 and is available on GitHub and NuGet.
The Duende.IdentityModel package is the base library for OIDC and OAuth 2.0 related protocol operations. It provides an object model to interact with the endpoints defined in the various OAuth and OpenId Connect specifications in the form of types to represent the requests and responses, extension methods to invoke requests constants defined in the specifications, such as standard scope, claim, and parameter names, and other convenience methods for performing common identity related operations.
Duende.IdentityModel targets .NET Standard 2.0, making it suitable for .NET and .NET Framework and is available on GitHub and NuGet.
Duende.IdentityModel.OidcClient is an OpenID Connect (OIDC) client library for mobile and native applications in .NET. It is a certified OIDC relying party and implements RFC 8252, “OAuth 2.0 for native Applications”. It provides types that describe OIDC requests and responses, low level methods to construct protocol state and handle responses, and higher level methods for logging in, logging out, retrieving userinfo, and refreshing tokens.
Duende.IdentityModel.OidcClient targets .NET Standard 2.0, making it suitable for .NET and .NET Framework and is available on GitHub and NuGet.
