WordPress Register CAPTCHA: Why You Need It and How to Enable It
One of the most common entry points for spam and fake accounts is the WordPress registration form. Without protection, bots can create thousands of accounts in minutes, filling your database with junk users and wasting server resources. Adding a CAPTCHA to the register form is the simplest and most effective way to keep your website secure.
Why add CAPTCHA to WordPress registration?
- 🚫 Stop bots from creating fake user accounts
- 🔒 Protect your site from automated attacks and spam
- ⚡ Save server resources by blocking malicious traffic early
- 📊 Keep your user database clean and accurate
How does it work?
CAPTCHA adds an extra security step to the registration process. Before an account can be created, users must confirm they are human (for example, by checking the “I’m not a robot” box). This simple action is enough to stop automated scripts while remaining easy for real visitors.
Protecting WooCommerce as well
If you run an online store, the WooCommerce register form on the My Account page is also a frequent target for bots. Enabling CAPTCHA here prevents fake customer accounts, keeping your orders and customer data safe.
