Why do healthcare environments struggle to move beyond passwords?

Why This Matters for Security Teams

Healthcare environments do not struggle with passwords because teams fail to understand authentication. They struggle because clinical systems, shared devices, shift-based workflows, and audit obligations create a dependency chain that makes simple replacement unrealistic. Passwords often become the universal fallback for EHR access, vendor tools, and legacy applications that were never designed for modern identity controls. That creates friction for clinicians and persistent risk for security teams.

The problem is broader than user convenience. Passwords are frequently embedded in account recovery, shared access patterns, and exception workflows, which means removing them can expose hidden operational dependencies. NHI Management Group’s Ultimate Guide to NHIs notes that 96% of organisations store secrets outside of secrets managers in vulnerable locations. That same operational sprawl appears in healthcare, where identity controls must fit bedside work, downtime procedures, and vendor connectivity at the same time. Current guidance in the NIST Cybersecurity Framework 2.0 still points teams toward risk-based, outcome-driven identity governance rather than a one-size-fits-all authentication mandate. In practice, many security teams discover the password problem only after a clinical workflow exception has already become permanent.

How It Works in Practice

Healthcare organisations usually move beyond passwords in stages, not through a single cutover. The first step is identifying where passwords are serving as a control substitute for poor application design, unmanaged shared access, or weak device trust. Then identity teams separate human authentication from workload access, contractor access, and device or service account authentication. That distinction matters because a nurse logging into a workstation, an infusion pump checking in, and a billing integration calling an API are not the same identity problem.

For human users, modern authentication can be layered with phishing-resistant methods, but that still leaves shared stations, offline scenarios, and emergency access. For non-human access, the better pattern is short-lived, scoped credentials and workload identity rather than static passwords. The operational goal is to reduce standing access and make every request explainable at runtime. That usually means:

• Replacing shared passwords with per-user authentication and session tracking where the application supports it.
• Using just-in-time access for privileged actions, with automatic expiry and revocation.
• Issuing workload credentials only for the task window, not as reusable secrets.
• Mapping clinical exceptions to documented break-glass controls with review after use.
• Inventorying where passwords still exist in vendor integrations, scripts, scanners, and service accounts.

This is where NHI governance becomes practical. The same NHIMG research shows that only 20% of organisations have formal offboarding and revocation processes for API keys, which is a warning sign for any hospital trying to modernise identity operations. Password removal fails when old workflows still depend on long-lived credentials, because the technical control changes faster than the clinical process around it.

Common Variations and Edge Cases

Tighter authentication often increases operational overhead, so healthcare leaders have to balance stronger identity controls against uptime, emergency care, and device compatibility. That tradeoff is real, especially in environments with legacy EHR modules, biomedical devices, and vendor-managed systems that cannot support modern sign-in flows. Best practice is evolving, and there is no universal standard for every clinical edge case.

Some environments should keep a narrow password fallback for downtime or break-glass use, but it must be heavily monitored, time-bound, and reviewed after activation. Others may need to retain passwords temporarily for older applications while wrapping them with compensating controls such as network segmentation, session logging, and privileged access management. For systems that cannot be modernised quickly, the priority is to reduce blast radius, not pretend the password has been eliminated.

The most difficult cases are third-party integrations and shared clinical terminals. Those settings often force exceptions that expand silently unless identity owners track them as operational risk. The broader NHI lesson is that passwords persist where governance is weakest, not where policy is least ambitious. That is why the Ultimate Guide to NHIs and the NIST Cybersecurity Framework 2.0 both support a staged, risk-led approach rather than a purely cosmetic “passwordless” announcement.
