What the current evidence supports

Human editorial judgment · 2026-08-20

Adopt with guardrails

Why
A billion-account-scale, vendor-default deployment with >1B authentications proves passkeys are production-ready and measurably faster/more phishing-resistant than passwords, but real 2026 implementation gaps (UV-flag trust, sync-domain secret extraction) and persistent user friction mean adopting teams must harden verification server-side rather than assume the passkey ceremony alone is sufficient.
Next
Track WebAuthn Level 3 + Digital Credentials API convergence for downstream passkey work; for any surface consuming Google (or other synced) passkeys, validate the user-verification assertion server-side rather than trusting the client-reported UV flag, per the 2026 Pass-ta-key finding
