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.

Passwordless authentication reduces password attack paths, but it does not eliminate identity governance. The article is correct to frame passwords as a structural weakness, especially where phishing and reset abuse dominate. But once the password disappears, the control problem moves to device registration, credential recovery, revocation, and auditability. Practitioners should read passwordless as a control shift, not a control conclusion.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to the Ultimate Guide to NHIs.
- Our research also shows that 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
A question worth separating out:
Q: Who is accountable when passwordless authentication fails?
A: Accountability sits with the identity, endpoint, and platform owners together, because passwordless depends on enrollment, device trust, and recovery orchestration. If a login works but revocation fails, the issue is not only authentication design. It is a governance failure across identity lifecycle and operational ownership.
