Frequently Asked Questions

Common questions about Captchinoo, admin login page protection with Google recaptcha

Not unless you want to. The Slide to unlock and Icon captcha styles work entirely on your own server with no account, no keys, and no external service. API keys are only required if you choose the Google reCAPTCHA option.

Visit the Google reCAPTCHA admin console, register your domain, and choose reCAPTCHA v2 → "I'm not a robot" Checkbox. Google will give you a Site key and a Secret key. Paste both into the plugin settings, then complete the verification step the plugin shows you. That last step confirms your keys actually work before the captcha goes live on your login page, so you can never lock yourself out with a wrong key.

The free version protects the WordPress login form (wp-login.php), which is the form targeted by brute force and credential stuffing bots. Other login forms on your site, such as a WooCommerce "My Account" form or a custom form from another plugin, are not affected.

The Icon captcha generates images on the fly and needs the PHP GD extension, which is not enabled on your server. Ask your host to enable GD, or simply use the Slide or Google reCAPTCHA option instead — both work without it.

Connect to your site by FTP or your host's file manager, go to /wp-content/plugins/, and rename the folder captchinoo-captcha-for-login-form-protection to anything else, for example captchinoo-disabled. WordPress will deactivate the plugin automatically and you can log in normally. This is why the plugin verifies your reCAPTCHA keys before enabling them — to prevent this situation in the first place.

No. Captchinoo loads nothing at all on the public pages of your site. Its scripts and styles are queued only on the login page, and only the ones belonging to the captcha style you selected.

Yes. WordPress login pages are excluded from page caching by every major caching plugin, so the captcha is always generated fresh and validated correctly.

Three additional protection layers on top of everything in the free version: two factor authentication (2FA), which asks the user to confirm the login from their mobile device so a stolen password alone is not enough; Google reCAPTCHA v3, which scores visitors invisibly in the background without ever interrupting them or hurting your conversion rate; and hCaptcha, an independent alternative for site owners who prefer not to route traffic through Google. See Captchinoo Pro for details.

No, and you do not need to. Activating the free version automatically deactivates the Pro version to prevent the two from conflicting. Pro contains everything the free plugin does, plus reCAPTCHA v3, hCaptcha, and 2FA.

Yes. All strings use the captchinoo-captcha-for-login-form-protection text domain and the plugin is ready for translation into any language.
