title: Custom Verification Code/Token in Asp .Net Identity
body: <p>I need to create short code (6 digits) for Email Confirmation using Asp.Net Identity.
  Currently, if I use </p>
  
  <pre><code>"GenerateEmailConfirmationTokenAsync" 
  </code></pre>
  
  <p>it provides me with very long code instead of this I want to generate a code which is only 6 digit in length. 
  Is there any way to achieve this how can I extend identity to provide such a feature. any leads towards this will be helpful.</p>
  
  <p>Thanks</p>
