What are Human Keys

Instead of relying solely on randomness, Human Keys derive security from human uniqueness—acting as an additional source of entropy. These attributes fall into three categories: What you are – Biometrics (fingerprints, iris patterns, voice). What you know – Passphrases, security questions, personal secrets. What you have – Secure devices, hardware wallets, physical tokens.

This sounds neat, and would be an absolutely amazing UX unlock for seed phrases.

I imagine there might be some challenges like e.g., 'what happens if you have serious eye problems and can't scan your iris anymore?' or 'what if you lose your hand and can't scan your fingerprints?'. With biometrics there's typically some fallback option, so maybe in this example it could be other guardian wallets or sth.

Anyway, this looks very cool. Thanks for sharing!
