I was debugging the source code in my new company to find the origin of the

OpenIdConnectProtocolInvalidNonceException

When the AuthenticationFailed notification is received, they check if User.Identity.IsAuthenticated

What I have tried:

When the exception is thrown, they get a AuthenticationFailed notification:

Notifications = new OpenIdConnectAuthenticationNotifications
    {
        AuthenticationFailed = n =>
            {
               if(n.Exception is OpenIdConnectProtocolInvalidNonceException)
                  {    
                     // This is the confusing line
                     if(n.OwinContext.Authentication.User.Identity.IsAuthenticated)
                         {
                             n.SkipToNextMiddleware();
                             return Task.FromResult(0);
                          }
                  }
             }
     }

Can the user be authenticated on AuthenticationFailed notification?
