What are customers saying about CAPTCHA 4WP?
Great efficient plugin with all the features and only loads resources on the pages where they are needed, helping to improve your sites overall SEO score.
Plugin works flawlessly. I use the free edition on my personal website and the premium one on my eCommerce site. It works perfectly with WordPress login & registration forms. I use the V2 Invisible, tested the forms using a bot and it displayed the image puzzle as expected.
I had an issue with my blog and they came back with the solution in hours!
