reCAPTCHA v3 in BotBlocker: User Verification and Key Setup Guide

BotBlocker offers seamless integration with reCAPTCHA v3, giving you a modern and invisible way to filter bots and suspicious activity on critical site pages. Here’s how it works, why it matters, and how to set it up in a few minutes.

Why Use reCAPTCHA v3?

  • Operates invisibly, assigning a risk score to each visitor—no user interaction or “I’m not a robot” checkbox required
  • Identifies bots and abusive behavior in the background, allowing real users through without friction
  • Can be used for login, registration, comments, checkout, or any other page where attacks and automation are a concern

How reCAPTCHA v3 Works in BotBlocker

  • When enabled, each visitor’s behavior is analyzed and scored from 0.0 (likely bot) to 1.0 (likely human)
  • BotBlocker uses this score to decide whether to allow, challenge, or block access based on your configured threshold
  • No visual interruption for real users—reCAPTCHA v3 works entirely behind the scenes

How to Create reCAPTCHA v3 Keys: Step-by-Step

  1. Open the reCAPTCHA Admin Console:
    https://www.google.com/recaptcha/admin
  2. Log in with your Google Account.
  3. Register a new site:
    • Enter a label for your project
    • Select “reCAPTCHA v3”
    • Enter your domain(s) (e.g., example.com, no “http://” or slashes)
    • Agree to the terms and submit
  4. Copy your Site Key and Secret Key:
    • These will be shown after registration (Site Key for frontend, Secret Key for backend)
  5. Add keys in WordPress admin:
    • Go to WordPress admin panel → BotBlocker Integrations → reCAPTCHA v3
    • Paste the Site Key and Secret Key into the relevant fields and save
  6. Test integration:
    • Visit a protected page as a regular visitor to ensure reCAPTCHA v3 is running (no widget, but analytics/logs will show requests scored)

Recommendations for Using reCAPTCHA v3

  • Use for login, registration, checkout, and any page at risk for bots or abuse
  • Set an appropriate score threshold in BotBlocker to balance security and user experience (0.5–0.7 recommended)
  • Rotate or update your keys if you change domains or move your site
