  // This script should change the password stored for the current user in your
  // database. It is executed when the user clicks on the confirmation link
  // after a reset password request.
  // The content and behavior of password confirmation emails can be customized
  // here: https://manage.auth0.com/#/emails
  // The `newPassword` parameter of this function is in plain text. It must be
  // hashed/salted to match whatever is stored in your database.
  //
  // There are three ways that this script can finish:
  // 1. The user's password was updated successfully:
  //     callback(null, true);
  // 2. The user's password was not updated:
  //     callback(null, false);
  // 3. Something went wrong while trying to reach your database:
  //     callback(new Error("my error message"));
  //
  // If an error is returned, it will be passed to the query string of the page
  // to which the user is being redirected after clicking the confirmation link.
  // For example, returning `callback(new Error("error"))` and redirecting to
  // https://example.com would redirect to the following URL:
  //     https://example.com?email=alice%40example.com&message=error&success=false
