Great and secure plugin

Hello everyone, i have installed this plugin almost 2 weeks ago,
it’s really awesome and saved my website from hacking after a long-suffering.
but i hope i can find an answer here to my question because im planning to download Cloudflare in my website.
but the problem Cloudflare has some options with the security level and creating a new page rule for the admin login, and that makes me worry both plugins maybe will not gonna works fine together.
