![]() To improve the Internet for everyone, we decided to open up the technology that powers our Managed Challenge to everyone in beta as a standalone product called Turnstile. We are opening our CAPTCHA replacement to everyone Cloudflare has a long track record of investing in user privacy, which we will continue with Turnstile. In addition, Turnstile never looks for cookies (like a login cookie), or uses cookies to collect or store information of any kind. While Turnstile has to look at some session data (like headers, user agent, and browser characteristics) to validate users without challenging them, Private Access Tokens allow us to minimize data collection by asking Apple to validate the device for us. Private Access Tokens are built directly into Turnstile. Rather than interrogating a device directly, we ask the device vendor to do it for us. Visitors using operating systems that support these tokens, including the upcoming versions of macOS or iOS, can now prove they’re human without completing a CAPTCHA or giving up personal data.īy collaborating with third parties like device manufacturers, who already have the data that would help us validate a device, we are able to abstract portions of the validation process, and confirm data without actually collecting, touching, or storing that data ourselves. In June, we announced an effort with Apple to use Private Access Tokens. Less data collection, more privacy, same security It's a simple, direct relationship that perfectly aligns our incentives. Meanwhile, at Cloudflare, we make money when customers choose us to protect their websites and make their services run better. Google says they don’t use this information for ad targeting, but at the end of the day, Google is an ad sales company. This tool is free to use, but in fact it has a privacy cost: you have to give your data to an ad sales company.Īccording to security researchers, one of the signals that Google uses to decide if you are malicious is whether you have a Google cookie in your browser, and if you have this cookie, Google will give you a higher score. If you are a small site using CAPTCHA today, you essentially have one option: an 800 pound gorilla with 98% of the CAPTCHA market share. While having to solve a CAPTCHA is a frustrating user experience, there is also a potential hidden tradeoff a website must make when using CAPTCHA. UX isn’t the only big problem with CAPTCHA - so is privacy Now anyone can take advantage of this same technology to stop using CAPTCHA on their own site. We talked in an earlier post about how we’ve used our Managed Challenge system to reduce our use of CAPTCHA by 91%. ![]() It automatically chooses from a rotating suite of non-intrusive browser challenges based on telemetry and client behavior exhibited during a session. Turnstile is our smart CAPTCHA alternative.
