How do I add basic security to my CometChat installation? (mobile only)

Please follow this guide ONLY if you are NOT using CometChat on your website. In other words- you are using CometChat ONLY in Android/iOS/Cordova/Ionic/Xamarin/Xamarin Forms apps. Visit the CometChat Admin Panel and head over to Settings -> Authentication. Under Security, enable “Enable Auth Key Verification?” setting. Clear your app cache and login to your app.
