Passwords are so 1990
summary
Argument that passwords are obsolete backed by a demo of the Web Authentication API using private/public key pairs and cryptographic challenges (16+ byte random buffers) instead of secrets. Shows USB, NFC, Bluetooth keys and built‑in authenticators like Touch ID, with about six people in the room owning USB keys. Walks through navigator.credentials.create and navigator.credentials.get, explains resident credentials, notes limits: no per-credential deletion, no cross‑device sync, Safari/iOS gaps, and recommends backup auth methods.
