YubiClicker, a clicker game that requires a physical security key

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=27141593 Cloudflare'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.

What it does

YubiClicker is Cookie Clicker, except every click is a FIDO2 assertion from a physical key tap. Climb a public leaderboard by out-tapping your opponents. YubiKey, Titan, Feitian, Solo, and Nitrokey all qualify.

In 2021, Cloudflare experimented with a CAPTCHA replacement called Cryptographic Attestation of Personhood that verified humans with a physical user presence check on a security key. The main criticism then was that the touch could be automated. Here though, for a game, I think that’s a cool way to win. Below is the full list of what should beat the boards, and what shouldn’t. If you find that any of these are possible, please email [email protected] . What the boards prove: you have a hardware key, and its touch sensor was activated serially. Though you’ll need a physical security key to get on the leaderboards, anyone with a passkey can register and play. Software…from yubiclicker.com

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
