This is a great way to keep you WordPress site secure and ensure no-one can login unless from specific IP addresses (i.e. your home, office etc).
Add this to your .htaccess file in the root directory:
<Files wp-login.php> Order Deny,Allow Deny from all Allow from xx.xx.xx.xx </Files>
Simply replace the x’s with your IP address/es.
