hCaptcha for WordPress


hCaptcha is a drop-in replacement for reCAPTCHA that pays website owners while preserving user privacy.

Do you use a captcha to keep out bots? hCaptcha protects user privacy, rewards websites, and helps companies get their data labeled. Help build a better web.

NOTE: This is a community-developed plugin. All integrations were submitted by developers who didn’t want to wait for a particular plugin to add native hCaptcha support.

If you see an integration that doesn’t work, or one that’s missing, please open a pull request:

However, you may wish to email the authors of plugins you’d like to support hCaptcha: it will usually take them only an hour or two to add native support if they choose to do so. This will simplify your use of hCaptcha, and is the best solution in the long run.

How hCaptcha Works

The purpose of a CAPTCHA is to distinguish between people and machines via a challenge-response test, and thus increase the cost of spamming or otherwise abusing websites by keeping out bots.

hCaptcha takes this idea and extends it by attempting to use those challenge answers for annotation, in an attempt to avoid simply wasting that effort. It is designed to solve the most labor intensive problem in machine learning: labeling massive amounts of data in a timely, affordable, and reliable way.

More data generally produces better results in training machine learning models. The recent success of deep models has led to increasingly large datasets, almost always with some human review. However, creating large human-reviewed datasets via Mechanical Turk, Figure Eight, etc. is both slow and expensive.

hCaptcha allows websites to earn rewards while serving this demand while blocking bots and other forms of abuse when a user needs to prove their humanity.

Privacy Notices

With the default configuration, this plugin does not:

  • track users by stealth;
  • write any user personal data to the database;
  • send any data to external servers;
  • use cookies.

Once you activate this plugin, the hCaptcha-answering user’s personal data, including their IP address, may be sent to the hCaptcha service.

Amazing plugin! Works really well and is much more privacy friendly then Google's Recaptcha. Keep up the good work 🙂

I tried google's reCaptcha, and it actually does not work well - many bots were still getting through, and registering on my website. After installing hCaptcha all the bot registrations have completely stopped coming through. hCaptcha is better, and I recommend it to everyone.
