   An example of how to extend time in your WordPress session by a year, simply enter this code into your `functions.php` or plugin. Other durations have been added to show different times hat can be set.

   add_filter ( 'auth_cookie_expiration', 'wpdev_login_session' );
   
   function wpdev_login_session( $expire ) { // Set login session limit in seconds
       return YEAR_IN_SECONDS;
       // return MONTH_IN_SECONDS;
       // return DAY_IN_SECONDS;
       // return HOUR_IN_SECONDS;
   }
