Hi,
There are Brute Force Settings in the WordPress admin panel -> Loginizer -> Brute Force page. Here you can define after how many failed login attempts to lock the IP address for how many minutes. You can also set Max Lockouts which defines after how many times the IP is locked it should be blocked for a longer time in hours set in Extended Lockout.
In order to blacklist an IP permanently you can either select the IPs from logs if they already appear in the failed login attempts logs or enter the desired IP under the “Blacklist IP” section on the same page.
Do let us know if you have any questions.
