What are common mistakes with Break-Glass Accounts?

What Break-Glass Accounts Are Meant to Do

Break-glass accounts are emergency access paths, not everyday admin identities. Their job is to keep critical systems reachable when normal authentication, federation, MFA, or privileged workflows are unavailable. That makes them useful during outages, lockouts, and recovery events, but only if they stay isolated, highly controlled, and hard to use by accident.

A common design mistake is treating break-glass access as just another admin login with a different label. The control objective is different: it should be a last-resort path with clear ownership, rare use, and obvious detection signals. When organisations blur that line, the account stops being an emergency safety net and becomes another standing privilege route.

For broader privileged-access design, NHIMG’s Privileged Access Management Guide explains how break-glass fits alongside vaulting, session controls, just-in-time access, and zero standing privilege.

Why Break-Glass Accounts Go Wrong in Practice

The most common failure is using the account for routine work. Once that happens, it becomes hard to distinguish genuine emergency use from normal administration, and teams often stop treating it as exceptional. Another frequent mistake is weak protection, such as a shared password, poor storage, no separate approval path, or no strong compensating control around the credential itself.

Monitoring failures are equally serious. If the account is not logged, alerted on, and periodically tested, it may only be discovered during an incident, when it is too late to validate the procedure or verify who used it. Break-glass procedures also fail when they are written but never practised, because the first real test then becomes a production recovery exercise.

That is why emergency-access design should be documented and rehearsed as part of recovery planning. NHIMG’s Break-Glass and Emergency Access Account Guide focuses on the practical controls around design, protection, monitoring, and testing.

What Good Break-Glass Governance Looks Like

Good governance starts with strict separation from normal admin paths. The account should not depend on the same everyday access controls it is supposed to bypass, but it should still be wrapped in compensating safeguards such as secure storage, strong logging, limited membership, and a clearly owned recovery process. If those safeguards are missing, the account is usually too convenient to be safe.

Practitioners should also expect to review the account regularly. That means checking whether the credential is still needed, whether recovery steps still work, whether the access path is still isolated, and whether the logging is complete enough to support post-incident review. In mature environments, break-glass access is periodically exercised under controlled conditions so the team knows the procedure works before a real outage proves otherwise.

Tabletop and recovery exercises help expose procedural gaps that configuration review alone will miss. NHIMG’s Tabletop Exercise Guide is useful when you want to test whether an emergency access process is actually usable under pressure.

Risk and Threat Considerations

Break-glass accounts concentrate privilege into a fallback path, so mistakes can turn a resilience feature into a high-impact security exposure. If the account is left enabled for normal use, weakly protected, or poorly monitored, an attacker only needs to find that one path to gain emergency-level access outside standard controls.

Failure mechanism: The account becomes a standing privileged backdoor, often with fewer guardrails than everyday admin access, so compromise or misuse is easier to miss and harder to contain.

Impact: A successful abuse can lead to privileged takeover, bypassed change controls, weak forensic visibility, and delayed detection during the very outage or incident when the account is most likely to be used.

Practitioner Guidance

What to verify: Confirm that the account is not part of day-to-day administration, that its credential is stored separately from normal admin secrets, and that every use generates a reviewable audit trail. If you cannot explain when it should be used and who can approve use, it is already too loosely governed.

Common mistake: Teams often test the login once during setup and assume the process is complete. The real control question is whether the account still works when normal identity infrastructure is degraded, whether the team can use it under pressure, and whether use is obvious enough to investigate immediately.

Practitioner takeaway: Treat break-glass access as a recovery control with blast-radius limits, not as a spare admin account. If it is easy to use routinely, it is usually too easy to abuse in an incident.
