Configure Applications with OIDC Discovery

You can configure applications with the OpenID Connect (OIDC) discovery documents found here:

https://YOUR_DOMAIN/.well-known/openid-configuration

For example, this is how to configure OIDC middleware for Katana v3 (OWIN):

  1. Install the nuget package: Microsoft.Owin.Security.OpenIdConnect (v3.x.x)

  2. Go to App_Start\Startup.Auth.cs and replace your implementation with the following:

          app.UseCookieAuthentication(new CookieAuthenticationOptions
          {
        AuthenticationType = CookieAuthenticationDefaults.AuthenticationType
          });
        
          app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
          {
        Authority = "https://YOUR_DOMAIN/",
        ClientId = "{YOUR_AUTH0_CLIENT_ID}",
        SignInAsAuthenticationType = CookieAuthenticationDefaults.AuthenticationType,
        ResponseType = "token",
        Notifications = new OpenIdConnectAuthenticationNotifications
        {
      // OPTIONAL: you can read/modify the claims that are populated based on the JWT
      SecurityTokenValidated = context =>
      {
        // add Auth0 Access Token as claim
        var accessToken = context.ProtocolMessage.AccessToken;
        if (!string.IsNullOrEmpty(accessToken))
        {
          context.AuthenticationTicket.Identity.AddClaim(new Claim("access_token", accessToken));
        }
        
        return Task.FromResult(0);
      }
    }
          });
        
        
    

RSA algorithm for JWTs

The OIDC middleware does not support JWTs signed with symmetric keys. Make sure you configure your app to use the RSA algorithm using public/private keys.

  1. Go to Dashboard > Settings.

  2. Click Show Advanced Settings.

  3. Set RS256 as JsonWebToken Token Signature Algorithm and click Save.

With this setting, Auth0 will issue JWTs signed with your private signing key. Your app will verify them with your public signing key.
