When your website means business.

Security, Users | Type: PHPHide Usernames from Hackers

When hackers discover your username, they have half the equation for logging in.

METHOD 1 - add to bottom of .htaccess, redirects www.domain.com/?author=1 queries back to homepage
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/wp-admin [NC]
RewriteCond %{QUERY_STRING} author=\d
RewriteRule ^ /? [L,R=301]
METHOD 2 - added to functions.php, does the same thing as above htaccess
function 
redirect_to_home_if_author_parameter() {
	$is_author_set = get_query_var( 'author', '' );
	if ( $is_author_set != '' && !is_admin()) {
		wp_redirect( home_url(), 301 );
		exit;
	}
}
add_action( 'template_redirect', 'redirect_to_home_if_author_parameter' );
