Ionic2 - Secure Storage in mobile application

Securing communication between mobile application and back-end server is crucial. We should authenticate the requests sent from mobile applications before serving them. Authentication may require username and password for the user, which most of the developers store into mobile local-storage.  Storing sensitive information in local-Storage is a very bad practice, instead you should use other options such as JWT tokens or Social providers. To get more information look to Security for Cordova mobile applications . An token is also an sensitive information, which we need to store somewhere, so what shall we do? Thank God cordova have such large community support, we will look for one of such plugin which can help us here.

Since Hybrid mobile applications are built over html and  javascript,  html don't support gesture events. There could be scenario's, where you wants to provide support for your hybrid mobile application. In such cases, we can use Hammer.JS  . Angular version 2 also provides support for Hammer.JS, about the same we will look into this post. Let's say we want to design a simple box, which we can rotate in any direction as shown Here we are trying to rotate the box in any direction by using Gesture events. To perform rotation we need to use two fingers. Let's see how we can implement the same in Ionic.
