title: AddDefaultTokenProviders: what is it and how to use those "default providers"?
body: <p>I found this in my <code>Startup.cs</code> file in <code>ConfigureServices</code> in a default Visual Studio 2015 ASP.NET 5 project:</p>
  
  <pre><code>services.AddIdentity&lt;ApplicationUser, IdentityRole&gt;()
                  .AddEntityFrameworkStores&lt;AuthorizationDbContext&gt;()
                  .AddDefaultTokenProviders();
  </code></pre>
  
  <p>What does it exactly do, and how to use those "default providers"? Does it configure all token-based authentication for me? Where can I read more about it?</p>
