hCaptcha.com has a "privacy pass", where if you create a user at hCaptcha.com, you can get passes to bypass the captcha itself (because you've already verified through other methods). This is not often used, because guess what? Not many people were bothered by captchas enough to create a user, because no one wants to create another user and be tracked (via privacy pass, across captcha-protected sites) through their user. This was mostly used by disabled users who couldn't pass hCaptcha's offerings.
Personally, I'm not interested in "logging in" or passing my "realness" via API from my device(s), as that's just another token to track an individual and their behaviors. Which is also why I haven't created any user for privacy pass myself, and would generally recommend that you not do so in any Apple, Google, etc., related system (not even hCaptcha, unless you're disabled and can't do the captcha itself).
I don't know what hCaptcha is doing nowadays.
But unless you're disabled, I wouldn't sign up or agree to pass this information from Apple, Google, etc.
