Break glass access needs accountability, not just emergency reach

At a glance

What this is: NHI Mgmt Group's analysis, drawing on OLOID's blog post: Break glass access is an emergency override for identity outages and urgent clinical needs, but shared logins and weak authentication undermine accountability.

Why it matters: IAM, PAM and healthcare security teams need emergency access that still works during outages while preserving attribution, auditability and post-event review.

By the numbers:

• Microsoft found that people sign in successfully with a passkey 98% of the time, compared with 32% for passwords.

Context

Break glass access is a controlled exception to normal identity governance. It exists because routine access paths can fail during outages, account lockouts or urgent care situations, and the recovery path has to remain usable when the rest of the stack is not.

The governance gap is accountability: emergency access is only defensible when the organisation can tie each use to one person, one reason and one reviewable event. Without that, the emergency path becomes a standing exception rather than a bounded control.

In healthcare and other high-availability environments, the same pattern shows up as emergency access procedure design. The control has to preserve continuity without weakening attribution, especially on shared devices and in time-sensitive workflows.

Key questions

Q: What should teams do when breakglass access is needed in production?

A: Breakglass access should be time-bound, purpose-bound, and automatically revoked after the incident or maintenance window ends. Teams also need logging that shows why the exception was granted, who used it, and what resources were touched so the exception is auditable later.

Q: Why does shared emergency access weaken accountability?

A: Shared emergency access weakens accountability because multiple people use the same credentials, so actions cannot be tied cleanly to one person. That breaks non-repudiation, obscures change history and makes access reviews, incident investigation and privileged access control harder. Individual named accounts with MFA, approval logging and time-bound elevation preserve traceability.

Q: How should teams secure emergency access accounts in an outage?

A: Secure emergency access accounts with tightly scoped, vaulted credentials, offline recovery procedures, MFA where possible and a tested rotation process after use. Keep the emergency path isolated outside the primary failure domain, with separate admin accounts, break-glass logging and clear ownership so outage access remains available without creating permanent standing privilege.

Q: What is the best way to audit break glass access on shared devices?

A: Audit break glass access by recording each use of the shared device, the named operator, the time, the reason and every privileged action taken. Use individual sign-in before any elevation, then review logs against approval records, session recording and device custody so the emergency access event stays attributable to one person.

Technical breakdown

What makes break glass access different from ordinary privileged access?

Break glass access is a pre-authorised exception path that exists specifically for failure conditions. Unlike routine privileged access, it is meant to bypass a broken primary control plane, such as SSO, federation, a PAM vault or a normal approval flow, while remaining limited in scope and duration. The important distinction is that emergency access is not supposed to be convenient normal access in disguise. It is a separately governed path with tighter purpose, stronger logging and explicit post-use handling. When the organisation cannot distinguish emergency use from everyday use, the control stops being an exception and starts becoming a hidden alternative login path. See the Privileged Access Management Guide.

Practical implication: Model break glass as a separate governed path with its own issuance, logging and review requirements.

Why do shared credentials make emergency access hard to audit?

A break glass account only remains accountable if the person using it is uniquely identifiable. Shared credentials collapse that attribution, so the audit trail shows the account name rather than the human who activated it. In an incident review, that ambiguity matters as much as the access itself because emergency overrides are supposed to answer who accessed what, when and why. The same problem appears on shared devices if users remain signed in or reuse a generic login. The access may be real, but the evidence chain is weak. That is a governance failure, not just a logging issue. See the Break-Glass and Emergency Access Account Guide.

Practical implication: Tie emergency access to individual sign-in so the audit trail names the actual user, not a shared account.

Why does emergency access fail when it depends on the same systems it is meant to bypass?

Emergency access is only useful if it still works when the main identity stack is unavailable. If the recovery account lives inside the same IdP, PAM vault or MFA dependency chain that has failed, the organisation has created a single point of failure disguised as resilience. That is why break glass design often requires local or offline authentication, separate credential storage and methods that do not rely on the outage-prone service. The mechanism matters because the emergency path must remain independent of the failure domain it is supposed to recover. Otherwise, the control disappears at the moment it is needed most.

Practical implication: Keep emergency credentials and authentication methods outside the failure domain of the primary identity stack.

NHI Mgmt Group analysis

Break glass access is a governance exception, not a privileged access shortcut. The control exists because routine identity paths can fail, but that does not make the emergency path interchangeable with ordinary admin access. The distinction matters for auditability, approvals and post-use review. If teams treat break glass as a convenience layer, they erase the very boundary that makes the control defensible.

Shared credentials create an accountability collapse in emergency access. When the audit record points to a generic login, the organisation loses the ability to prove who invoked the override and whether the action was justified. That weakens incident review, compliance evidence and deterrence at the same time. The issue is not merely poor attribution; it is a control that no longer supports responsibility.

Emergency access must survive the outage domain it is designed to recover. A recovery account that depends on the same IdP, MFA service or vault it is supposed to bypass is structurally fragile. The control boundary has to sit outside the failure mode, or the emergency path becomes unavailable exactly when operations need it most. That is why resilience and identity governance have to be designed together.

Break-glass design exposes a named concept: accountable emergency override. The useful control is not just access under duress, but access that remains individually attributable, logged and reviewable after the event. OLOID’s examples show that frontline workflows, shared devices and healthcare overrides all push the same requirement into sharp relief. Practitioners should treat accountability as the defining property of emergency access, not an optional add-on.

Frontline and clinical environments reveal the real break glass problem. Shared workstations, fast-moving shifts and time-sensitive care make people more likely to bypass slow sign-in paths. That pressure is operational, not malicious, but it still produces weak evidence if the session is not tied to one verified identity. The practical lesson is that usable sign-in is part of emergency governance, not separate from it.

What this signals

Accountable emergency override: The real control objective is not simply restoring access during failure, but preserving a provable chain of responsibility when normal identity paths are unavailable. That means recovery design has to balance continuity, attribution and reviewability at the same time.

Break glass design is now a frontline identity problem as much as a back-office PAM problem. Shared devices, fast sign-in pressure and outage recovery requirements converge on one question: can the organisation still prove who used the override after the fact?

The next maturity step is to treat emergency access as part of the broader identity lifecycle, not a one-off exception. Credentials, authentication methods and review procedures all need a defined end state after use, or the temporary override becomes a standing risk.

For practitioners

• Define explicit emergency trigger criteria Document which outage states, access failures or care situations justify emergency access, and require a named approver or escalation path for each one.
• Keep at least two emergency accounts independent Place recovery accounts outside the primary IdP and avoid making them depend on the same federation or vault path they are meant to bypass.
• Use phishing-resistant authentication for break glass Prefer passkeys or certificate-based authentication for emergency accounts and store the recovery factors separately from the devices that hold them.
• Require reason capture and post-use review Log the account used, the resource accessed, the time of use and the stated reason, then review the session promptly after activation.
• Remove shared sign-ins from frontline workflows Use individual sign-in on shared devices so emergency access events can be attributed to one person instead of a generic workstation session.

Key takeaways

• Emergency access is necessary when routine identity controls fail, but it only remains defensible if every use is attributable and reviewable.
• Shared logins, weak authentication and unmonitored accounts turn a recovery mechanism into an investigation problem.
• The control that matters most is not just emergency reach, but the ability to prove who used it, why they used it and what happened next.

Key terms

• Break-glass Access: Break-glass access is an emergency path that bypasses normal access controls when standard authentication fails or a critical incident demands immediate intervention. It must be tightly time-bound, logged, and reviewed, because it exists to restore operations without becoming a permanent back door.
• Emergency Access Account: An Emergency Access Account is a highly restricted backup identity used when normal authentication or administrative controls are unavailable. In IAM and PAM, it provides break-glass access for critical recovery, usually with strong protections such as offline storage, tight monitoring, dual control, and immediate review after use.
• Break-the-Glass Override: Break-the-Glass Override is an emergency access path that bypasses normal approval or control checks so a user can get into a system during an urgent failure. It is usually tightly restricted, heavily logged and reviewed after use, because it creates exceptional access that temporarily relaxes ordinary identity and authorisation rules.
• Phishing-Resistant Authentication: Phishing-resistant authentication proves identity without relying on a user to approve a prompt or reveal a reusable secret. It typically binds access to a device, key, or cryptographic proof that an attacker cannot easily reuse or coerce. This approach reduces reliance on human judgment at login time.
