title: Auto verify a user in Amazon Cognito User Pools
body: <p>I get this error that a user can't change/reset their passwords if I don't set up the email verification in user pools:</p>
  
  <pre><code>You have not selected either email or phone number verification, so your users will not be able to recover their passwords without contacting you for support.
  </code></pre>
  
  <p>I want to be able to user forgot password as instructed in the ios user pool tutorial but will need to verify the email using a Pre Sign Up lamba trigger.</p>
  
  <p>How do you use the lambda trigger? I know how to write Lambda functions but not sure on how to verify the email address (so that all emails are verified and I don't care if a user signs up with a garbage one for now). Thanks.</p>
