 # Authenticate users with WS-Federation in ASP.NET Core

 This tutorial demonstrates how to enable users to sign in with a WS-Federation authentication provider like Active Directory Federation Services (ADFS) or [Microsoft Entra ID](/azure/active-directory/). It uses the ASP.NET Core sample app described in [Facebook, Google, and external provider authentication](xref:security/authentication/social/index).
 
 For ASP.NET Core apps, WS-Federation support is provided by [Microsoft.AspNetCore.Authentication.WsFederation](https://www.nuget.org/packages/Microsoft.AspNetCore.Authentication.WsFederation). This component is ported from [Microsoft.Owin.Security.WsFederation](https://www.nuget.org/packages/Microsoft.Owin.Security.WsFederation) and shares many of that component's mechanics. However, the components differ in a couple of important ways.

 ## Use WS-Federation without ASP.NET Core Identity
 
 The WS-Federation middleware can be used without Identity. For example:

 ## Add WS-Federation as an external login provider for ASP.NET Core Identity
 
 * Add a dependency on [Microsoft.AspNetCore.Authentication.WsFederation](https://www.nuget.org/packages/Microsoft.AspNetCore.Authentication.WsFederation) to the project.
 
 * Add WS-Federation to `Startup.ConfigureServices`:
