 * Hello,
 * I have a few sites that are reporting that the following file has been modified:**
   class-two-factor-core.php**
 * The only change was removing this line on **line 705**:
 * > do_action( ‘two_factor_user_authenticated’, $user );
 * What affect would that have on the plugin? Perhaps this would allow bypassing
   the two factor requirement?
 * Thank you!
 * Jacob Hill

 * Hi! This hook was added in one of the recent releases and it can’t be used for
   anything apart from detecting when a user is logged-in after the second-factor
   authentications.
