Zero trust or passwordless: which risk does IAM still leave?

TL;DR: Passwordless authentication and zero trust cut password dependence only when recovery, authorisation, and monitoring are managed together, according to Soffid. IAM programmes that split those controls leave the exception path to define access risk.

Editorial analysis by NHI Mgmt Group, based on content published by Soffid: “Latest cybersecurity trends for Businesses”.

Key questions

Q: When does zero trust fail for non-human identities?

A: Zero trust fails for non-human identities when organisations focus only on human authentication and network segmentation.

Q: Why does SSO reduce password risk but not eliminate access risk?

A: SSO removes repeated password entry, which reduces password fatigue and lowers exposure to reuse and phishing.

Q: How should security teams implement passwordless authentication without creating new recovery risk?

A: Security teams should remove passwords from both primary login and recovery paths, then require stronger proofing for reset workflows than for normal sign-in.

Practitioner guidance

  • Align passwordless recovery with assurance levels Treat account recovery, device reset, and step-up prompts as part of the authentication policy, not a separate helpdesk process.
  • Re-scope entitlements for zero trust Review whether users still carry broad role access after the first verification step.
  • Use behavioural telemetry to support identity decisions Correlate login patterns, session behaviour, and device context so anomalous activity is visible before it becomes material.

Bottom line: Passwordless authentication and zero trust reduce reliance on passwords, but they only work when recovery, authorisation, and monitoring are governed as one system.

Passwordless reduces credential exposure, but it does not remove the need for identity governance. The article correctly treats password removal as a way to shrink the theft and replay surface, not as a complete security model. Organisations still have to govern enrolment, recovery, step-up verification, and access scope across the full identity lifecycle. The practitioner conclusion is that passwordless is a control shift, not a control finish line.

Identity programmes are moving toward continuous assurance rather than one-time verification. Passwordless authentication, zero trust, and behavioural detection are strongest when they are designed as one control surface that governs proof, privilege, and observation together.

A question worth separating out:

Q: How do security teams balance AI-based detection with least privilege?

A: Use AI-based detection to surface abnormal behaviour, but do not rely on it to compensate for excessive access. The best outcome comes when identity policies already constrain what an account can reach, because that makes unusual activity easier to identify and contain.
