title: Nativescript storing user tokens
body: <p>Is it a good practice or am i missing something? I wan't to store user access and refresh token returned from a Web API in application-settings or do we have password vault equivalent in nativescript or do we use sql lite 
  My requirement is that my tokens should not be allowed to access by other apps installed on device. Thanks for the help in advance
