IdentityModel is a .NET Standard helper library for claims-based identity, OAuth 2.0, and OpenID Connect. It provides request/response object models, extension methods, and specification constants for interacting with OAuth and OIDC endpoints. Note: the project is being rebranded to Duende.IdentityModel and moved to the DuendeSoftware/foss repository.

Use cases

  • make OAuth 2.0 token requests from .NET
  • interact with OpenID Connect discovery and token endpoints
  • work with standard claims, scopes, and parameter names
  • validate and parse identity tokens in .NET apps
  • implement client credentials or authorization code flows in C#

When to choose

  • you need a lightweight .NET helper for OAuth 2.0 / OIDC protocol operations
  • you are building clients against IdentityServer or any compliant OIDC provider
  • you want specification constants and request/response models instead of raw HTTP calls

When to avoid

  • starting new projects - use the rebranded Duende.IdentityModel package instead
  • you need a full authentication UI or user session management rather than protocol helpers
  • you are not on the .NET platform
