Redefining Security: From Passwords to Biometrics and Digital Signatures
summary
Passwords cause most breaches — 81% of breaches — and are brittle against AI brute force and social engineering. The recommended fix is WebAuthn + passkeys and hardware security keys (near-zero compromise unless the key is stolen), with biometrics and PINs kept local. A demo app Sparky demo shows login and digital signing implemented in TypeScript + Kadena + Pact, minting an NFT as proof with transactions taking ~30s–1min.
