title: Email Token Expiring After 15 mins - Asp Identity 2.0 API
body: <p>I'm facing a strange issue in Asp Dot Net Identity API 2.0 API.</p>
  
  <p>When an user signs up, I send a confirmation email to the user. And if the user confirms his / her account within 15 mins of signing up, the "ConfirmEmailAsync" method seems to be working.</p>
  
  <p>But after 15 mins, if I try to confirm the email address, I'm getting a "Invalid Token" error.</p>
  
  <p>Is there a way to set the token expiry time?</p>
  
  <p>A really frustrating issue and it's becoming very hard to troubleshoot.</p>
  
  <p>Can anyone help please?</p>
