Journey to passwordless
summary
Explains how passwordless actually works with concrete protocols and devices: FIDO2/WebAuthn, U2F and UAF using public key cryptography, platform authenticators (Touch ID, Face ID) and roaming keys like YubiKey. Shows the register/challenge/sign flow, how user presence vs user verification changes security, and how discoverable credentials enable username‑less logins. Calls out real problems: browser/platform inconsistencies, recovery and downgrade paths, and that passwords persist. Notes ~4 billion biometric‑capable devices and upcoming cross‑platform passkey backups to ease adoption.
