AspNet.Security.OAuth.Providers

AspNet.Security.OAuth.Providers is a collection of security middleware that you can use in your ASP.NET Core application to support social authentication providers like GitHub, Twitter/X or Dropbox. It is directly inspired by Jerrie Pelser's initiative, Owin.Security.Providers.

The latest official release can be found on NuGet and the nightly builds on MyGet.

Getting started

Adding social authentication to your application is a breeze and just requires a few lines in your Startup class:

public void ConfigureServices(IServiceCollection services)
{
 services.AddAuthentication(options => { /* Authentication options */ })
 .AddGitHub(options =>
 {
 options.ClientId = "49e302895d8b09ea5656";
 options.ClientSecret = "98f1bf028608901e9df91d64ee61536fe562064b";
 });
}

public void Configure(IApplicationBuilder app)
{
 app.UseAuthentication();
 app.UseAuthorization();
}

See the /samples directory for a complete sample using ASP.NET Core MVC and supporting multiple social providers.

Migrating to OpenIddict

The OpenIddict client and its 100+ web providers have significant advantages over the simpler OAuth 2.0-only authentication handler that is used by the aspnet-contrib providers:

• OpenIddict fully supports OpenID Connect, which allows enforcing additional security checks for providers that implement it.
• The OpenIddict client is stateful and provides built-in countermeasures against nonce/token replay attacks.
• While the aspnet-contrib providers only support the OAuth 2.0 code flow, the OpenIddict providers support additional flows, including the OpenID Connect hybrid flow, the OAuth 2.0 client credentials grant, the resource owner password credentials grant or the refresh token grant.
• The OpenIddict client supports OAuth 2.0 token introspection and OAuth 2.0 token revocation.
• OpenIddict uses OAuth 2.0 and OpenID Connect server configuration discovery to avoid hardcoding the endpoint URIs of a provider when possible, making the OpenIddict web providers more robust and more future-proof.
• While the aspnet-contrib providers require targeting the latest ASP.NET Core version, the OpenIddict web providers can be used in any supported version. They can also be used in ASP.NET 4.6.1+ websites and Windows/Linux desktop applications.
• OpenIddict uses Microsoft.Extensions.Http.Polly (or Microsoft.Extensions.Http.Resilience on .NET 8+) to make backchannel HTTP communications less prone to transient network errors.

Providers

Links to the latest stable and nightly NuGet packages for each provider, as well as a link to their integration documentation are listed in the table below.

Documentation for the providers' settings can be found .

If a provider you're looking for does not exist, consider making a PR to add one.
