title: ASP.NET Web API 2 - single sign-on
body: <p>Is there any way to achieve single sign-on with separate <code>ASP.NET Web API 2</code> services and <code>OWIN Bearer Token Authentication</code> ? I want to have two separate <code>web.api</code> applications and don't want to sign in to second app when I'm alredy logged in first application. </p>
