Get Started with WordPress
This guide takes you from a fresh download to a WordPress site that's automatically protected — no code required.
Before you begin
You'll need:
- A WordPress site compatible with WordPress up to version 7.0, running PHP 8.1 or later.
- Admin access to the WordPress dashboard, to upload and activate the plugin.
Step 1 — Download the plugin
The plugin isn't distributed through the WordPress Plugin Directory, so it's installed manually. Download the latest altcha.zip from the GitHub releases page.
Step 2 — Upload and activate
- In your WordPress dashboard, go to Plugins → Add Plugin → Upload Plugin.
- Choose the
altcha.zipfile you downloaded and click Install Now. - Go to Plugins, find ALTCHA: Anti-Spam Protection, and click Activate.
A new ALTCHA menu appears in your admin sidebar.
Step 3 — Confirm it's protecting your site
The plugin protects WordPress login, registration, and comment forms automatically — no configuration needed. Open one of those forms and check your browser's developer console; you should see a log line from the ALTCHA Interceptor when the form is submitted. See Troubleshooting if you don't.
Step 4 — Protect a custom form (optional)
Most popular form plugins (WPForms, Gravity Forms, Contact Form 7, WooCommerce, and more) are protected automatically too — see the full list on the Advanced page.
To add ALTCHA to a custom form or template, drop in the shortcode:
[altcha]See Advanced for shortcode attributes.
