reCAPTCHA v5 Platform Sandbox

This developer release operates completely offline. It demonstrates how to maintain the psychological safety of the traditional checkbox user interface while fully removing legacy tracking cookies, fingerprint scripts, and image puzzle loops.

1. Live Sandbox Interactive Demo

Adjust the simulation parameters below to test how the widget reacts to trusted users versus automated botnets without loading a single external tracking layer.

2. Implementation & Integration Tutorial

Deploying reCAPTCHA v5 is simple. Because it loads entirely local assets, it maintains absolute zero data privacy leakage (GDPR/PIPL compliant).

Step A: Embed the Tracking-Free Interface Element

Drop the self-hosted structural component directly adjacent to your form submit inputs:

<div class="rc-v5-anchor">
  <div class="rc-v5-body">
    <div class="rc-v5-checkbox" onclick="executeV5Check()"></div>
    <div class="rc-v5-label">I'm not a robot</div>
  </div>
</div>

Step B: Bind Passive Attestation Token Flow

The system relies strictly on modern cryptographic infrastructure rather than visual grid puzzles. When verified, a backend token is appended safely into the form data payload:

function executeV5Check() {
  // 1. Kick off localized spinning interface state
  activateSpinnerUI();

  // 2. Query hardware layer / Private Access Token (PAT)
  window.crypto.subtle.digest("SHA-256", new Uint8Array([/* Client Telemetry */]))
    .then(() => {
      // Validate with Edge backend (Cloudflare Turnstile Core)
      let payloadToken = "v5_attestation_passed_" + btoa(Date.now().toString());
      document.getElementById("form-token").value = payloadToken;
      showGreenCheckmark();
    })
    .catch(() => {
      // If suspicious, do NOT throw an image box loop. Reset layout immediately.
      triggerInstantWidgetReset();
    });
}
