YubiClicker: A clicker game requiring a physical security key (YubiKey).

YubiClicker, while presented as a game, subtly explores the utility of physical security keys beyond traditional authentication. It highlights the potential for YubiKey taps to serve as a novel form of human verification, distinct from CAPTCHAs. This concept, previously explored by Cloudflare, suggests a future where physical interaction with security hardware could validate user presence or intent in various applications. While a game, it acts as a proof-of-concept for leveraging hardware security features for non-security-critical, yet verification-dependent, interactions, potentially opening new avenues for user engagement and bot detection.
