About the Extension
This extension reliably protects your forms from spam registrations and unwanted contact requests – without any annoying captcha queries for your customers.
Instead of visible puzzles or image selection, the extension works with an invisible captcha that checks in the background whether it is a genuine user action. This maintains the user-friendliness of your shop while effectively blocking automated spam bots.
The extension is quick and easy to set up and is ready to use immediately. No complex settings or external services are required.
Optionally, you can customise the behaviour of the captcha to suit your requirements by setting the minimum time for submitting forms or disabling mouse and touch tracking if necessary.
Under the ‘Captcha IP Lists’ menu item, you can selectively allow or block individual IP addresses. Whitelisted IPs bypass the Captcha check entirely – ideal for internal testing. Blacklisted IPs, on the other hand, are consistently blocked.
In the Captcha statistics, you’ll find clear daily statistics. These show you at a glance how many Captchas were triggered per day and how many of these were successfully solved or rejected. This allows you to quickly spot unusual activity.
