That’s so cool. Beter use an additional passphrase on the face-enabled seed phrase in case of an $5 wrench attack.
Just built Passkey39: a library that generates the same crypto private key every time you use your Face ID or Touch ID. No more seed phrases to lose, your biometric authentication becomes your deterministic wallet key through WebAuthn magic.
What do you think? I'm curious if it's a good or bad idea 🤔
