By default, WHMCS provides basic security for administrative access by denying access after a set number of invalid logins. However, there’s much more potential for enhanced security. With WHMCS User and IP Extended, you can:
Lock administrative users to a specific IP address
Allow admin logins only from specific countries
Block admin logins from specific countries
No more manual editing of .htaccess files to add admin IP addresses. We offer a ‘lockout’ script that any logged-in admin can call via browser. If not logged in, users will be redirected to the admin login page.
