title: Device id is null on computer
body: <p>From Ionic <a href="https://ionicframework.com/docs/native/device/" rel="nofollow noreferrer">doc</a> I'm using ionic native device plugin to get my device id.</p>
  
  <p>The problem is when I test app on computer (in Chrome browser) device id is <code>null</code>. however when I run my app on mobile the it gives a unique alpha numeric string. </p>
  
  <p>I want to know why it is null or computer. and is there any difference in device id and mac address. I think mac address is also a unique number for each device.</p>
