reCAPTCHA Enterprise offers up to 10,000 assessments per month at no cost and also provides additional features. Other features such as real time analytics provide the best place to start for most developers. Get started here.
Yes, you can use both reCAPTCHA (non-Enterprise version) and reCAPTCHA Enterprise. Typically the third party solution asks for your public key and either your secret key or your API key. Make sure to only provide your secret key and API key to trusted third parties.
The migration process takes 5-10 minutes to complete and requires no code changes.
reCAPTCHA v3 is for site owners who want more data about their traffic. For more information, see the reCAPTCHA v3 developer guide.
We support security and usability for v2.
For more information about reCAPTCHA v2 and v3 differences, see versions comparison.
You are allowed to hide the badge as long as you include the reCAPTCHA branding visibly in the user flow. Please include the following text:
This site is protected by reCAPTCHA and the Google
<a href="https://policies.google.com/privacy">Privacy Policy</a> and
<a href="https://policies.google.com/terms">Terms of Service</a> apply.
For example:
Note: if you choose to hide the badge, please use
.grecaptcha-badge { visibility: hidden; }
For reCAPTCHA v3, create a separate key for testing environments. Scores may not be accurate as reCAPTCHA v3 relies on seeing real traffic.
For reCAPTCHA v2, use the following test keys. You will always get No CAPTCHA and all verification requests will pass.
The reCAPTCHA widget will show a warning message to ensure it's not used for production traffic.
To avoid stepping into the reCAPTCHA code while debugging other JavaScript on your site, add the reCAPTCHA script /recaptcha__.+\.js$ to your browser's ignore list. For instructions for Chrome, refer to Ignore a custom list of scripts. Similar features are available in other browsers.
reCAPTCHA reports daily stats in the admin console.
Yes, please use "www.recaptcha.net" in your code in circumstances when "www.google.com" is not accessible.
Yes. reCAPTCHA offers two themes, light and dark, as shown below. To choose a theme, simply set the data-theme attribute in the grecaptcha.render parameter.
Light theme:
Dark theme:
The JavaScript API available for Invisible reCAPTCHA also works for v3. Simply use the JavaScript API to explicitly render reCAPTCHA with a v3 site key to access options such as repositioning the badge or changing the theme.
When rendering reCAPTCHA v3 with this method, remember to set the size parameter to 'invisible' and use the client ID returned by grecaptcha.render when calling grecaptcha.execute instead of the site key.
If you are seeing this error, your reCAPTCHA site key is no longer valid. To activate, please register a new key and follow the instructions on that page.
This typically occurs if the reCAPTCHA widget HTML element is programmatically removed sometime after the end user clicks on the checkbox. We recommend using the grecaptcha.reset() javascript function to reset the reCAPTCHA widget.
We recommend using the nonce-based approach documented with CSP3. Make sure to include your nonce in the reCAPTCHA api.js script tag, and we'll handle the rest.
Note: reCAPTCHA also works with 'strict-dynamic' on browsers that support it.
Alternatively, please add the following values to the directives:
localhost domains are not supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the reCAPTCHA Enterprise console or to the reCAPTCHA console, as appropriate, to update your list of supported domains. We advise to use separate keys for development and production, and to only allow localhost on your development site key.
This is a focusing bug on Apple's side that we've reported to them. It affects users only on iOS 10 and only on some sites. If you are affected, a workaround is to move the reCAPTCHA widget higher or lower on the page, or use reCAPTCHA v3.
If you were directed to this page from the reCAPTCHA widget, you would have seen a message that said "We're sorry, but your computer or network may be sending automated queries. To protect our users, we can't process your request right now."
This can unfortunately happen to good users for a few reasons:
To troubleshoot these issues, please look at the unusual traffic help page, or try again later.
