They say it's a QR code challenge, resistant to bots, but what does it to? How does it work?

    the qr itself is just a link to a recaptcha web page with a unique identifier in the url.

    the magic is all hidden in the required app that's linked to your google account and device, and the interactions that take place between it and google's servers once it sees that code or link.

    I looked for info and didn't find anything.

    Obviously you could decode the code on the device that's showing it, so why not also provide a link?

    I have to assume that it's because the mobile device must be one where they can check that you're only running google approved software (play integrity or whatever it's called these days, maybe the apple equivalent).
