Explains how WebAuthn/Passkeys replace passwords with public‑key credentials, backing the claim with adoption and risk numbers: 81% of breaches tied to stolen passwords, second‑factor uptake moving from 28% to 52%. Shows working code: a maintained webauthn‑ruby gem, Rails 8 generator, demos and QR portability for cross‑device passkeys. Notes real deployments (GitHub, Shopify, government logins), tradeoffs for device‑bound vs roaming passkeys, and what actually validates on the server.
