KeyCAPTCHA Unique Technologies:
* Instead of guessing symbols, our CAPTCHA offers visitors to complete an easy interactive task.
* If KeyCAPTCHA hasn't been solved correctly, page refreshing doesn't take place that allows the user not to fill in the form repeatedly. It occurs since there is an initial checkup of CAPTCHAs in the KeyCAPTCHA servers before sending a filled-in form to the protected web server.
* Our CAPTCHA also can be used even if your hosting provider blocks all outgoing connections.

1. Register on and log-in to our site
2. Add your site URL to a Site list.
3. Follow the CAPTCHA installation instructions in our Wizard.

To upgrade KeyCAPTCHA plugin you have to uninstall the previous version.

I installed captcha to stop our forms being spammed. As our site was bespoke and didnt use normal Joomla forms captcha wouldnt work automatically. I opened a support ticket and the problem was solved within minutes. Andrey logged into the system and changed the code to make it work. Excellent service highly recommended. Oh yes and the spam of 50 emails a day has instantly stopped. Great result.

Since ReCaptcha used to be broken, we had to look for another captcha. We found this one. Anybody can solve a puzzle! It works well and the support is great. Any time I had a question, it got answered immediately, which is rare in a free tool.

I'm moving back to reCaptcha though, which has everything to do with the costs for the paid version (to remove the "free version" tag etc). As the cost is per website per month or year, it gets to be a lot for a bunch of sites. Pity!

Great service .. Very satisfied operational staff working on emerging issues. Grow!

I gave a fantastic review but this site said that my review was fraudulent. Guess I have to have a dang backround check to post something honest. I'm really annoyed, but great captcha

New and not-boring extention to secure many input panel (tipically attacked by robots).

Great support to newbies like me.

Life can be easy

This plugin works excellent in combination with my template. Just follow the instructions, get your key from the owners website, put it in the plugin, activate Captcha's in your global settings and off you go. What could I want more??? Thank you guys!
