how to hide wp-admin page icons

function is_login_page() {
    return in_array($GLOBALS['pagenow'], array('wp-login.php', 'wp-register.php'));
}
add_filter('wsl_render_auth_widget_alter_widget_css','wsl_remove_all_but_comments',10);

//$widget_css = apply_filters( 'wsl_render_auth_widget_alter_widget_css', $widget_css, $current_page_url );

function wsl_remove_all_but_comments( ){

if(is_login_page()){
	echo '<style> .wp-social-login-widget{ display:none;} </style>';
}else{
  //not the page you are looking for
}

Quick and dirty should work tho in functions.php
