title: ASP.NET Identity, "Remember Me" and cookie timeout
body: <p>In my MVC Startup.Auth.cs file, there is this code:</p>
  
  <pre><code>Provider = new CookieAuthenticationProvider
                  {
                      OnValidateIdentity = SecurityStampValidator
                          .OnValidateIdentity&lt;ApplicationUserManager, ApplicationUser, int&gt;(
                              validateInterval: TimeSpan.FromMinutes(30),
                              regenerateIdentityCallback: (manager, user) =&gt;
                                  user.GenerateUserIdentityAsync(manager),
                              getUserIdCallback: (id) =&gt; (id.GetUserId&lt;int&gt;()))
                  }
  </code></pre>
  
  <p>If I understand this correctly, the login cookie will expire in 30 minutes. Which means the user will be forced to log back in, in 30 minutes. If this is correct, what is the value of having the user select "Remember Me" on the login page if the login cookie expires in 30 minutes?</p>
