OpenCart Community

Current Version: v2025-3-24 (release notes)

OpenCart Versions: 1.5.0.x - 4.1.0.x

To Purchase: Visit Clear Thinking or opencart.com



This extension allows you to quickly and easily add a captcha to your customer, affiliate, and admin login pages, as well as the front-end "forgot your password" form. This will help prevent bot and hacker login attempts on your site.

• Upload and go — no core file modifications are necessary. The extension utilizes vQmod for OpenCart 1.5.x, ocMod for OpenCart 2.x/3.0, and Event hooks for OpenCart 4.
• Take advantage of the built-in extension updater. All that's required is to enter your current license key and click "Update".
• Uses Google's secure reCAPTCHA technology for the admin login pages, and your chosen Captcha extension for the front-end login pages.
• Displays a proper error message when the captcha does not verify correctly, editable in the vQmod file.
• Adds captcha verification for the standard customer login, the checkout customer login, the affiliate login, the admin login, and the "forgot your password" forms.
• Optionally add a list of IP addresses to ignore, so certain customers or administrators can log in without seeing the captcha.

Updated to v230.1

Release Notes:
- Confirmed: compatibility with OpenCart 2.3.0.x

Updated to v300.1

Due to limitations in the opencart.com license system, a new extension was released on opencart.com for OpenCart 3.0 compatibility. However, free updates are still available for anyone that has purchased the extension in July 2016 or after --- just contact Clear Thinking here: http://www.getclearthinking.com/contact
