title: How to create a security stamp value for asp.net identity (IUserSecurityStampStore)
body: <p>In my MVC-5 application, I have to <strong>create security stamp values manually</strong>. The current implementation of the identity team seems to use a guid.</p>
  
  <pre><code>Guid.NewGuid().ToString("D")
  </code></pre>
  
  <p>Is it safe to create a new Guid myself to use as a new security stamp value or will this lead to problems in future implementations of asp.net identity?<br>
  Is there a method to let the identity framework create such a stamp-value for me so that my implementation is safe for future changes?</p>
