4. Update incident response. Add playbooks for:

o Revoking authenticators en masse

o Remote wipe / MDM workflows

o Containing abused recovery flows

o Rapid re-issue of keys to critical users

5. Track the ecosystem. Passkey standards and platform support evolve (proximity checks,
attestation, anti-spoofing). Keep architecture reviews continuous, not one-and-done

Conclusion: Embrace the Future—Eyes Open

Passwordless especially passkeys is a major leap forward. It slashes entire classes of attacks and
simplifies life for users and admins alike. But passwordless is not riskless. The threat frontier moves: to
devices, enrollment and recovery, cloud sync, and human manipulation. Organizations that succeed
won’t just “turn on passkeys”; they’ll engineer the whole lifecycle authenticator issuance, user verification,
recovery, monitoring, and incident response with the same rigor once reserved for passwords.

Adopt the technology, absolutely. Pair it with policy, process, and monitoring, and you’ll earn both the
phishing resistance you want and the resilience you need.
