Where do I edit login form

How or where i can edit the login form used in the widget and login panel ? (child theme) - want to add shortcode to add login via fb buttons

ok found my anser finally in rtp-widgets by adding

<?php echo do_shortcode('[TheChamp-Login]');?><?php //echo do_shortcode('[clef_render_login_button]');?>

after line 53 - can i copy this file to my child theme to “keep” changes after updates?
