Passwordless authentication: are IAM controls really keeping up?

TL;DR: Passwordless authentication reduces phishing exposure and password-reset overhead by replacing static secrets with FIDO2, passkeys, biometrics, and badges, according to Imprivata. The governance challenge is that stronger login flows improve user experience but do not remove the need for lifecycle control, device binding, and privileged access oversight.

NHIMG editorial — based on content published by Imprivata: passwordless authentication and its security implications

By the numbers:

• 81% of hacker-caused security incidents are linked to, ked to stolen or weak passwords.
• 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.

Questions worth separating out

Q: How should organisations roll out passwordless authentication without weakening recovery controls?

A: Start by mapping every fallback path, including helpdesk resets, backup codes, and device replacement flows.

Q: When does passwordless authentication reduce risk and when does it simply move the risk?

A: It reduces risk when the organisation replaces reusable secrets with device-bound cryptographic credentials and also governs issuance, revocation, and recovery.

Q: How do security teams know whether passwordless authentication is actually improving assurance?

A: Look for fewer password resets, fewer phishing-driven takeovers, and tighter control over enrolled devices and recovery events.

Practitioner guidance

• Harden recovery before expanding passwordless Remove weak fallback paths such as email-only resets, helpdesk overrides, and shared recovery codes.
• Bind authentication to lifecycle events Trigger revocation, re-enrolment, and access review when a device is lost, replaced, or reassigned.
• Separate biometric unlock from identity assurance Document whether biometrics are used only to release a local key or to satisfy the authentication decision itself.
