For the basic functionality, it’s working well. If you use anything special or external library it depends on your project. So because it’s OK for me it doesn’t ii mean it will work for you.
This problem with Chrome is not a bug, when you call your app this way https://www.yourapp.com,SC will redirect it to https://www.yourapp.com/app_login.com/index.php. Chrome sometime thing that this is phishing and that you are doing it to deceive the user.
If you tell your customers to use directly the login URL https://www.yourapp.com/app_login/index.php Google should not complain.,
