DeveloperReplace CAPTCHA with privacy-first human verification from Checkify.
Checkify helps WordPress site owners reduce CAPTCHA friction by using privacy-first human verification.
Instead of asking visitors to solve puzzles, Checkify lets visitors complete a verification flow and return a verification result to the WordPress site. This can be used on pages, forms, or custom flows where the site owner wants to request human verification.
Checkify is designed around privacy-first verification. The WordPress site receives a verification result, not unnecessary personal identity data.
Features
- CAPTCHA alternative for WordPress
- Privacy-first human verification
- Site connection using a QR code
- Local QR rendering in the browser
- Shortcode support using [checkify_verify]
- Live Checkify API integration
- No external QR code generation service
How it works
- Install and activate the Checkify plugin.
- Open the Checkify settings page in WordPress.
- Generate a connection QR code.
- Scan the QR code in the Checkify app to connect your WordPress site.
- Create or select a Checkify Pass for human verification.
- Paste the Checkify Pass ID into the plugin settings.
- Add [checkify_verify] to the page where you want to show human verification.
The shortcode creates a verification request, renders a QR code locally in the visitor’s browser, polls for verification status, and stores a temporary local verification result for that visitor.
External services
This plugin connects to Checkify services to provide human verification.
Service used:
- Checkify API: https://api.checkify.me
- Checkify website: https://checkify.me
The plugin connects to Checkify when:
- A site administrator creates a site connection claim.
- A site administrator polls the status of a site connection claim.
- A connected WordPress site creates a verification request.
- A connected WordPress site checks the status of a verification request.
- A connected WordPress site confirms a completed verification result.
The plugin may send the following data to Checkify services:

- A Checkify installation identifier.
- A Checkify Pass or launcher identifier configured by the site administrator.
- Verification request identifiers.
- Verification status tokens.

The plugin does not use an external QR code generation service. QR codes are generated locally in the visitor’s browser using the bundled QRCode.js library.
