title: Design recommendations for Xamarin Forms Login scenario
body: <p>I am looking for some best practice advice. I have a mobile application that has 4 functional elements. Out of the 4 only 1 requires the user to be authenticated.</p>
  <p>For the authentication I have built a login page. So first I am checking if an application level property is setup. If that is true then the app does not need authentication. If that is not set I am loading a login form hosted on a content page.</p>
  <p>The login page/ form has a backing ViewModel.</p>
  <p>The PROBLEM I am trying to solve is that after the user has logged in from the login page and navigates to the next page, the back button takes user back to the login page.</p>
  <p>The scenario I would like is that when user reaches a specific page, from that page back should go back to another page not the login page.</p>
  <p>MainPage --&gt; Login --&gt; Dashboard</p>
  <p>Dashboard(Back) --&gt; Login (Not desired)</p>
  <p><strong>Dashboard(Back) --&gt; MainPage (Desired)</strong></p>
  <p>Can somebody please help with this? I am looking for some guidance.</p>
  <p>Regards.</p>
