TL;DR: Passkeys are phishing-resistant, device-bound credentials that store only a public key on the service side, while passwords remain vulnerable to reuse, spoofing, and compromise, according to Keeper Security. The shift matters because authentication design still has to cover mixed estates where passkeys and passwords coexist, and that creates governance and recovery gaps.
Editorial analysis by NHI Mgmt Group, based on content published by Keeper Security: “Passkey vs Password: Which Should I Use?”.
Key questions
Q: What should security teams do first when passkeys are not available everywhere?
A: Start by mapping where passkeys are supported and where passwords must remain in place, then segment your rollout by application criticality and user population.
Q: Why do passwords create more risk than passkeys in modern login environments?
A: Passwords are transferable secrets, so they can be phished, reused, guessed, or exposed in a breach.
Q: What are the signs that a passwordless rollout is not gaining traction?
A: A weak rollout usually shows up as continued password dependence, low security key adoption, and inconsistent policy enforcement across user groups.
Practitioner guidance
- Map where passkeys are actually supported Inventory applications, devices, and user groups to identify where passwordless sign-in can replace passwords without breaking access.
- Keep passwords covered by stronger controls Where passwords remain required, enforce long unique passwords and multi-factor authentication so legacy access does not become the weakest remaining path.
- Redesign account recovery for device-bound login Review how users regain access after device loss or authenticator change, since passkeys shift the recovery problem from secret reset to trusted re-enrolment.
Bottom line: Passkeys materially reduce phishing and breach exposure because they use device-bound cryptographic proof instead of a reusable shared secret.

Passkeys change the control model because the secret is no longer what the user knows. The security boundary moves from memorised credential handling to device-bound proof of possession plus local unlock. That makes phishing resistance structural rather than behavioural, which is why passkeys materially outperform passwords in modern login design. Practitioners should treat this as an authentication architecture change, not a cosmetic login option.
A question worth separating out:
Q: How should teams balance password controls with MFA and lockout policies?
A: Use password controls to reduce guessability, but do not expect them to carry the full defence. MFA limits the value of a stolen password, and lockout policies reduce brute-force speed, but both need to be tuned so they do not create operational harm. The right balance is layered control with monitoring that confirms the settings are actually working.
