FAQ

Defender is built to add all the best hardening and website security recommendations used by the pros without having to become a security expert. This means you get all the most effective and proven protection methods other services provide with fewer settings, one-click hardening and faster setup.

If you’re the administrator and you’ve been locked out due to multiple failed login attempts, Defender offers two options:

Option #1: Use the “Unlock Me” feature:

Click the Unlock Me button on the login page and enter your username or the email address linked to your site. You’ll receive an email with a secure link to unlock your account and regain access — no technical steps needed.

Option #2: Use the manual method (if email doesn’t work):

Add the following code to your theme’s functions.php file, located in the main directory of your active theme.

add_filter( 'ip_lockout_default_whitelist_ip', function ( $ips ) {   $ip    = 'YOUR IP HERE';   $ips[] = $ip;   return $ips; } );

Replace “YOUR IP HERE” with your actual IP address (you can use a tool like whatsmyip to find it.)
