title: ASP.NET Identity OAuth2 and Limited Input Devices
body: <p>I need to use the OAuth infrastructure to log in limited input devices like Apple Watch with ASP.NET Identity and OAuth 2.</p>
  
  <p>The iOS app and the ASP.NET Web App work fine together but I can't find any example about Apple Watch and the digit code.</p>
  
  <p>I'd like the Youtube/Netflix interface with a 4 digit code to input in another logged device but I don't know where to start. The Google documentation refers to it but it only explain the process, no code there.</p>
  
  <p>I'm using <code>ASP.NET Identity</code> for OAuth server implementation and <code>OAuthSwift</code> for iOS/watchOS code but the documentation is really poor for the two frameworks.</p>
  
  <p>Somebody already found a solution for this problem or has some examples to study?</p>
