Thibault Meunier, writing on the Cloudflare blog:
We want to get rid of CAPTCHAs completely. The idea is rather simple: a real human should be able to touch or look at their device to prove they are human, without revealing their identity. We want you to be able to prove that you are human without revealing which human you are! You may ask if this is even possible? And the answer is: Yes! We’re starting with trusted USB keys (like YubiKey) that have been around for a while, but increasingly phones and computers come equipped with this ability by default.
Let’s face it, CAPTCHAs are annoying. I may have clicked on thousands of little photos of traffic lights so far, and it’s been an annoyance every single time.
If you have a YubiKey, you can try out the flow on https://cloudflarechallenge.com — a test website setup by Cloudflare.
I’d love to see where this initiative goes.
