Description
I thought cookie clicker but with yubikey taps might be funny, and this is a proof of concept. Cloudflare did something similar in 2021, pitching yubikey-proven taps as a captcha replacement:https://news.ycombinator.com/item?id=27141593Cloudflare's idea of proving personhood with yubikey taps wasn't well received at the time. But here for a silly game, I think the idea holds up better. We can prove that you have a key, and serially tapped it a lot. If you automate activating the touch sensor on a physical key, you might be able to do a bit better. That's cool and you deserve to win.

Could you build this?
Partial While the game concept and clicker loop are trivial, the backend requires complex WebAuthn direct attestation verification, FIDO Metadata Service (MDS3) certificate chain validation, and AAGUID filtering.
What it would actually take: The backend needs a custom WebAuthn implementation configured for direct attestation rather than standard login. It must parse CBOR attestation statements, validate x5c certificate chains against the official FIDO MDS3 blob, verify hardware root certificates, and enforce that each tap provides a serial User Presence (UP) assertion to prevent replay or virtual authenticator bypasses. This requires solid WebAuthn/cryptographic engineering expertise to ensure the hardware key guarantees hold up against spoofing.
