Best plugin I have ever installed

I have always installed this plugin on all WP websites that I create or manage. Nothing significant seems to have happened.
However lately I have been monitoring one of my websites and noticed heightened attempts to log in without my permission.
I lowered the number of attempts to 2 and increased lockout periods.
I have also turned option to get notifications every time login fails and login IP attempts get locked out.
I couldn’t be happier.
This has worked as the best protection from hacks, protection to lock out intruder IP’s etc.
So far over 450 failed attempts and over 250 permanently locked out IP’s
Thank you for the protection
