> we may see captchas blocking humans That article comes at the same time I am blocked by PayPal's stupid captcha because I don't have a "web GPU" (whatever that shit is) in my browsers (even on Chromium) despite having 2FA enabled. A good reminder that I should stop using PayPal for my subscriptions and donations. In addition to that, we have web sites broken because they don't implement properly the CloudFlare protection and give me 403 or 500 errors. We really need a new web.

WebGPU requires Vulkan or a Vulkan-like API to be present and not blacklisted. I wonder if they are fingerprinting the nuances of your system's Vulkan implementation? Not sure why WebGL based fingerprinting wouldn't be enough for this -- maybe because folks wishing to get around the fingerprinting have already made deterministic OpenGL renderers.

  I do not think my system and/or hardware supports Vulkan, but I never had issues with PayPal's invisible CAPTCHA (is it invisible or I just never see it?).

    It was yet another captcha that looks like a puzzle right after the 2FA step.

      Oh, I think I came across that (I think it was PayPal? I actually don't know because I rarely see any on PayPal) before. It worked for me, but I do not have Vulkan, I believe. So I am not sure what happened in your case. You could call up their support (I did a few times before because I got locked out). This was a few months ago, I could get to a human pretty quickly (at least at that time). It was a sweet lady, and she spoke English (only). My problem was resolved within minutes. That said, in your case they would probably tell you to try a different browser, or even a different IP address (VPNs may have an issue).

  After some tweaking it was definitely the fingerprinting that got me. I don't know why we still have this after the push of the industry for 2FA and Passkeys.

That's fun. I have a coworker who had to disable that on his laptop, because ads were crashing his machine. Yeah, it's a hardware problem and he should get a new one, but that's a lot of trouble (and may not be feasible for someone who bought their own machine).
