TL;DR: Passwordless IAM removes password-centric attack paths and replaces them with biometrics, hardware tokens, and device-based verification, according to 1Kosmos. The security gain is real, but the governance problem shifts to proofing quality, fallback controls, auditability, and lifecycle management across user populations.
Editorial analysis by NHI Mgmt Group, based on content published by 1Kosmos: “The Truth About Passwordless IAM Authentication”.
Key questions
Q: What breaks when organisations use passwordless login without verifying identity upfront?
A: Passwordless login can still fail if it removes the password but does not prove who the user is with sufficient assurance.
Q: Why does passwordless IAM still need audit trails?
A: Because security teams must be able to prove how the identity was enrolled, what factor authenticated the user, and how exceptions were handled.
Q: How should IAM teams manage fallback and recovery in passwordless programmes?
A: Treat fallback and recovery as part of the authentication design, not as a convenience layer.
Practitioner guidance
- Define enrolment assurance thresholds Set different proofing requirements for workforce, contractor, customer, and privileged accounts so the same passwordless method does not create the same assurance level everywhere.
- Harden recovery and fallback flows Classify device replacement, help-desk reset, and alternate factor recovery as security events that require strong verification and complete audit logging.
- Review authentication evidence retention Ensure logs capture who enrolled the identity, which factor was accepted, what fallback was used, and whether re-proofing occurred after risk changes.
Bottom line: Passwordless IAM reduces exposure to password theft and reuse, but it does not remove the need to prove who the user is at enrolment and recovery.

Passwordless IAM shifts the governance burden from secret protection to proof assurance. Removing passwords eliminates one of the most exploited identity artefacts, but it does not simplify governance. The programme now has to prove enrolment integrity, factor binding, and recovery discipline across the lifecycle. That makes assurance quality, not login convenience, the real control objective.
A few things that frame the scale:
- eBay's passkey data shows 55-60% of passkey adoption happens on mobile, against around 20% on desktop.
A question worth separating out:
Q: Should organisations replace MFA with passwordless authentication?
A: Organisations should not treat this as a simple replacement question. MFA is still useful where passwordless is not yet available, but passwordless raises the security baseline by removing the password as the primary failure point. The right path is to use MFA as a bridge and passwordless as the destination.
