Invisible recaptcha

hello!

recently I’m facing brute force attacks on my website.

my hosting provider has forced me to use htaccess file to allow only few ip addresses.

i convinces them that for buddypress to be used this is not a solution so they asked me to try with recaptcha on login.

i installed an invisible recaptcha plugin and activated it on all pages, but it doesn’t seem to work with the login pop up window.

is there a way to make that work? Or do I have to force my users to use the standard WordPress login page?

thanks
