Secure answer stored as WordPress transient (no PHP sessions)
Beautiful light and dark-themed login page design
Customizable accent color with live preview

FAQ

Does this require any API keys?: No. Everything runs on your WordPress server using PHP and WordPress transients.
Will this slow down my site?: No. The plugin only loads on the login page and admin settings page.
What if the captcha expires?: Each captcha token is valid for 10 minutes. If it expires, the user just needs to refresh the login page.
What happens when I uninstall the plugin?: All plugin settings and captcha transients are automatically cleaned from your database when you delete the plugin via the WordPress admin.

I’m use this plugin as additional security layer for my login page, since the native cloudflare didn’t have manual tick button to ensure only human can proceed with login. So after looking around, this math verification fits well into my login page, which Im paired it with cloudflare. Works well so far. Thanks!
