First, log in to your HeatShield account and click the WordPress navigation link to list your WordPress sites.
Select the name of the WordPress site where you want to manage the login whitelist.
Click on Whitelist.
Input the IPv4 or IPv6 address into the IP Address field and add a note in the Note field if desired.
Click the Add to Whitelist button.
After you've added an IP address to the whitelist, that IP address will not be blocked even if there are repeated WordPress login failures from that IP address. If the IP address had previously been blocked, the existing block was automatically removed when you whitelisted the IP address.
