Passwordless authentication: what IAM teams should phase first

TL;DR: Most organisations are not eliminating passwords outright, but reducing dependence through phased adoption that balances security, usability, and operations, according to SSH Communications Security. Passwordless succeeds when teams treat authentication as a migration path, not a big bang replacement for existing IAM patterns.

Editorial analysis by NHI Mgmt Group, based on content published by SSH Communications Security: “The Journey towards Passwordless”.

Key questions

Q: What should IAM teams review when moving toward passwordless access?

A: Review recovery processes, device trust assumptions, policy exceptions, and how authentication events feed access governance.

Q: Why does passwordless adoption usually need a phased rollout?

A: Because most identity estates contain legacy applications, recovery paths, and user journeys that cannot all change at once.

Q: What are the biggest operational mistakes teams make with passwordless migration?

A: The most common mistake is treating passwordless as a login project instead of a credential governance project.

Practitioner guidance

  • Map password dependencies by access journey Inventory where passwords still exist across workforce apps, admin paths, recovery flows, and shared services.
  • Define the hybrid authentication state Document which user groups, applications, and exception cases will remain password-based during migration, and make those boundaries visible to IAM, help desk, and application owners.
  • Target the highest-friction authentication flows first Start with login paths that produce repeated password resets, frequent lockouts, or the clearest phishing exposure, because those are the places where passwordless yields measurable operational and security gains.

Bottom line: Passwordless authentication is most effective when teams reduce password dependence in phases instead of trying to eliminate every password at once.

Passwordless is a migration discipline, not a product swap. The article correctly frames passwordless as staged reduction in password dependence rather than immediate elimination. That matters because IAM programmes fail when they confuse a target control with a rollout method. The practitioner conclusion is that authentication modernisation needs sequencing, governance, and support design, not just a preferred login method.

A question worth separating out:

Q: How do organisations know whether passwordless access is actually improving security?

A: Look for reduced password dependence, fewer lockouts, lower help desk reset volume, and stronger control over high-risk workflows such as shared workstation access and privileged clinical systems. If user friction drops while identity assurance rises, the programme is moving in the right direction.
