The purpose of the tag is to state the name and version of the application tool used to create your website. The bad thing about this is that it openly declares what software and version you are using – if that software and version are out of date and subject to exploitation by a hack you are leaving yourself wide open.
In the WordPress installation folder, go to and open the functions.php file from your theme folder or just edit the file directly in WordPress via Appearance>Editor>functions.php – it has a onscreen title of theme functions and at the bottom of the file add this following php snippet:
// hide the meta tag generator from head and rss
function disable_meta_generator() {
return '';
}
add_filter('the_generator','disable_meta_generator');
remove_action('wp_head', 'wp_generator');
Update the file, and reload the home page, check the source code and you will see the generator tag for WordPress is no longer visible. More importantly always keep your WordPress version up to date.
