Passwordless access and MFA fatigue: what IAM teams should change

TL;DR: Human error still drives a large share of breaches, with IBM cited in the source article saying 90% of successful cyberattacks and 70% of data breaches originate at endpoint devices. Imprivata’s argument is that passwordless authentication, single sign-on, and automated credential rotation reduce risky workarounds by removing friction rather than relying on better user discipline.

NHIMG editorial — based on content published by Imprivata: As Employees Remain the Weakest Link, Experts Say It’s Time to Eliminate Passwords

By the numbers:

Questions worth separating out

Q: How should organisations reduce password-related risk without slowing employees down?

A: Use passwordless authentication for the highest-friction access points, then layer SSO and automated secret rotation where users still interact with shared or operational credentials.

Q: Why do complex password policies often fail in real workplaces?

A: They fail because complexity does not eliminate human behaviour, it often increases the chance of workarounds such as reuse, shared sign-ins, or sticky sessions on shared devices.

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

A: Look for fewer password resets, fewer help desk tickets, fewer shared logins, and less session reuse on common devices.

Practitioner guidance

  • Replace password-heavy workflows with passwordless access Start with the most repetitive, high-friction login paths in frontline and shift-based environments, then measure whether password resets, help desk calls, and unsafe sign-in workarounds decline.
  • Use single sign-on to cut repeated authentication prompts Reduce the number of independent logins employees face across core applications so they are less likely to reuse credentials, share sessions, or leave devices signed in.
  • Automate credential rotation for shared access paths Prioritise credentials used on shared workstations, mobile devices, and high-turnover operational systems so manual secret handling does not become the weakest point in the access chain.

What's in the full article

Imprivata's full article covers the practical access-design argument this post intentionally leaves at a higher level:

  • Why passwordless login reduces friction in fast-paced operational settings where repeated authentication drives workarounds
  • How automated credential rotation changes accountability for shared devices and shared access paths
  • Why single sign-on can improve both usability and visibility without asking employees to manage more passwords
  • How the article frames secure access as a human-performance problem rather than a training problem

Passwordless access is a human IAM control, but its governance value extends into broader identity hygiene. When users stop working around password friction, organisations reduce the behavioural pressure that often spills into credential reuse, shared sign-ins, and unsafe session handling. That is not just a user-experience improvement. It is a structural reduction in avoidable identity risk, especially in operational environments where access speed and safety are both non-negotiable. Practitioners should treat friction as a security variable, not only an adoption metric.

A few things that frame the scale:

  • 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
  • Lack of credential rotation is cited as the top cause of NHI-related attacks by 45% of organisations, followed by inadequate monitoring and logging at 37%.

A question worth separating out:

Q: Who is accountable when employees use unsafe access workarounds?

A: Accountability sits with the programme that designed the workflow, not only with the employee who took the shortcut. IAM, security architecture, and operations teams all influence whether secure access is practical under real workload pressure. Frameworks such as NIST Cybersecurity Framework 2.0 emphasise that governance must make the secure path sustainable.
