<p>Hubsine Spam Protection with Fallback for reCAPTCHA integrates Google reCAPTCHA V3 and V2 with WordPress native forms and popular form plugins. Choose between three protection modes and configure each form independently.</p>
<p><strong>Protection modes:</strong></p>
<ul>
<li><strong>V3 only</strong> — Invisible score-based protection. No user interaction required. Submissions scoring below the threshold are blocked silently.</li>
<li><strong>V2 only</strong> — Classic “I’m not a robot” checkbox. Full user interaction required.</li>
<li><strong>V3 with V2 fallback (recommended)</strong> — V3 runs invisibly first. Only users who score below the threshold are shown the V2 checkbox, giving real users a second chance.</li>
</ul>
<p><strong>Supported forms:</strong></p>
<ul>
<li>WordPress login form</li>
<li>WordPress registration form</li>
<li>WordPress lost password form</li>
<li>WordPress comment form</li>
<li>Contact Form 7 (via <code>[hubsine_recaptcha]</code> tag)</li>
<li>Ninja Forms (via a draggable field in the form builder)</li>
</ul>
<p><strong>Key features:</strong></p>
<ul>
<li>Internal token system — the Google V3 token is pre-verified server-side before form submission. Submissions carry a short-lived signed token instead of a raw Google token, reducing API latency on submit.</li>
<li>Per-form configuration — set the V3 action string and score threshold independently for each form.</li>
<li>Token auto-refresh — the internal token is refreshed in the background so users on long forms always have a valid token.</li>
<li>No dependencies — no Composer, no npm, no jQuery. Plain PHP 7.4+ and vanilla JavaScript.</li>
<li>WordPress.org compliant — no obfuscated code, no outbound calls other than the documented Google API.</li>
</ul>

CAPTCHA 4WP – Antispam CAPTCHA solution for WordPress

The plugin authors removed CF7 support for the plugin with no prior warning, so all websites that were using it for their CF7 forms broke (I had in the range of 20 websites where the form validation had been silently broken this way), so they would display a broken "[anr_nocaptcha g-recaptcha-response]" shortcode. I rarely take my time to write a review for anything, but this definitely deserved it. You should warn users so that they choose to update or not; not simply make this change and let all existing CF7 forms break. Shame on you.

The plugin authors let all their sites break


For the past week, my site has been inundated with fake account registrations. Since adding this plugin yesterday there haven't been any new ones. I'm hopeful that it won't cause any problems for students signing up for my courses.


Yay no fake registrations today!


5 stars, no notes - MU/multisite support greatly appreciated


Perfect for me and MU support
