I am new to MVC 5 authentication. Currently I tried Google Authorization using Owin The code in startup.Auth.cs
var googleOAuth2Authenticati
Try this it may work. Its works for my case
app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions() { ClientId = "YourClintId", ClientSecret = "YourSecretKey", CallbackPath = new PathString("/Account/ExternalLoginCallback") });
