Frequently Asked Questions

Common questions about GateCHA CAPTCHA

GateCHA is a self-hosted CAPTCHA management service that wraps the ALTCHA proof-of-work protocol. It provides API key management, multi-site support, and an analytics dashboard. See the GateCHA website for more information.

Instead of asking users to solve image puzzles, the browser solves a small computational challenge in the background. This is invisible to legitimate users but expensive for bots trying to submit forms at scale.

The API key is used in the browser to fetch challenges, similar to how reCAPTCHA and hCaptcha use site keys. You can restrict your API key to specific domains in your GateCHA dashboard for additional security.

Only to your own GateCHA instance. No data is sent to any third-party service. See the External Services section below.

Yes, use the [gatecha] shortcode to place the widget anywhere. Then verify the altcha POST field server-side.

Define a bypass token in your wp-config.php: define( 'GATECHA_BYPASS_TOKEN', 'your-secret-test-token' ); Then in your tests, set the altcha hidden input to this token before submitting the form:

The plugin will accept the token as a valid verification without contacting the GateCHA server. Never define this constant in production.
