title: Multiple application authentication using one login
body: <p>I have an application running on asp.net with Identity for user management.</p>
  
  <p>Now I am in production of another application having technologies asp.net core and Angular 7.</p>
  
  <p>I have tried using same DB for both application for login but it didn't worked since Identity on .net and .net core have different Hashing algorithms.</p>
  
  <p>can I use my .net app verification same for .net core and angular 7 app by just giving any Button link from the first application?</p>
  
  <p>When I proceed like above i found some problems listing below:-</p>
  
  <ul>
  <li>How to avoid user directly accessing the second application .net core ?</li>
  </ul>
  
  <p>How can i proceed with this scenario?</p>
  
  <p>Any help will be appreciated.</p>
