Break glass accounts should be treated as exceptional, high-risk access paths, not routine admin credentials. The core controls are minimal use, strong authentication, continuous monitoring, logged approvals, periodic testing, and regular credential rotation. Teams should also isolate these accounts from standard admin roles, limit remote access, and maintain clear documentation so emergency access remains available without becoming a standing privilege risk.
What Break Glass Means in a Multi-Cloud Context
break glass account are emergency access paths that exist so responders can restore service when normal admin workflows fail, but in multi-cloud environments they need a stricter definition than “backup admin.” Each cloud has its own identity plane, logging model, and privilege structure, so the account must be designed for emergency use across environments without becoming a portable standing privilege.
That usually means the account is limited to a very small set of break-fix actions, has strong authentication, is isolated from day-to-day administration, and is governed like a controlled exception. The operating question is not whether the account is powerful, but whether its power is bounded, observable, and recoverable after use.
Multi-cloud design also changes the trust model. A break glass account that can reach AWS, Azure, and GCP should not behave like a general-purpose superuser in every tenant and subscription. The tighter pattern is to keep the emergency path separate from normal access workflows, then bind it to specific recovery scenarios, documented ownership, and explicit activation criteria.
Controls That Make Emergency Access Safe Enough to Use
The most important control is to make emergency access exceptional in both policy and implementation. That starts with a unique account or tightly segregated role set, then continues with strong authentication, credential rotation, and session logging. For identity and privilege hygiene, the same logic that applies to high-risk non-human access also applies here, especially where accounts are shared, long-lived, or hard to observe. NHIMG’s NHI Lifecycle Management Guide is a useful reference point for lifecycle, rotation, and offboarding discipline, and the broader pattern is reflected in Top 10 NHI Issues.
Access should be time-bound and approval-based wherever the environment still allows it. If pre-approval is impossible during an outage, the account still needs compensating controls, such as a documented emergency trigger, post-use review, and a mandatory rotation step before it is re-armed. Logging must capture who enabled the account, what actions were taken, from where, and against which cloud control plane.
Isolation matters as much as authentication. A break glass account should not inherit ordinary admin group membership, should not be used for routine change work, and should not be left with broad remote access paths by default. The safer design is to make the emergency path narrow, auditable, and hard to confuse with standard operations. That also reduces the chance that an operator reuses it because it is easier than the approved path.
Operational Discipline for Testing, Rotation, and Recovery
Emergency access only works if it is tested before it is needed. Regular drills should verify that the account can be opened, authenticated, monitored, and closed in each cloud platform. This is where many programs fail: the account exists, but the team does not know whether the credentials still work, the logs are complete, or the post-use rotation process is executable under pressure. The statistics in NHIMG’s 2025 State of NHIs and Secrets in Cybersecurity and Ultimate Guide to Non-Human Identities reinforce why rotation and visibility cannot be treated as optional hygiene.
After every use, the account should be rotated or reissued, and the event should trigger a review of whether the emergency path was used correctly. If the account was needed because normal privileged access failed, that is a control issue as well as an availability issue. If it was used because the standard process was too slow, the answer is usually to improve the normal path rather than normalise break glass use.
Documentation is not secondary. Teams need a runbook that states when the account may be used, who can authorise it, how access is revoked or rotated afterward, and how evidence is preserved for audit and incident review. Without that, emergency access becomes a hidden privileged backdoor rather than a controlled recovery mechanism. For practitioner context on misuse and lifecycle failure, Coupang Signing Key Breach is a useful illustration of why unrevoked credentials remain dangerous after the original event has passed.
Risk and Threat Considerations
Break glass accounts are high-value targets because they often combine broad privilege, emergency urgency, and weaker day-to-day scrutiny. In multi-cloud environments, that risk increases when the same emergency pattern is replicated across platforms without consistent logging, rotation, and ownership. The main danger is not only misuse during a crisis, but also quiet persistence after the crisis has ended.
Failure mechanism: Attackers seek the least monitored privileged path, then exploit static credentials, weak segregation, or poor post-use rotation to keep emergency access alive beyond its intended window.
Impact: A compromised break glass account can expose every connected cloud environment, bypass normal approval gates, and turn a recovery mechanism into a full administrative foothold.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while CIS Controls v8, NIST Zero Trust (SP 800-207) and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 — Secrets and Credential Management | Break glass accounts rely on high-risk credentials that need strict rotation and control. |
| NHI-03 — Privilege and Access Governance | Emergency accounts must stay exceptional, isolated, and minimally privileged. | |
| NHI-06 — Lifecycle, Offboarding and Recertification | Emergency accounts need testing, review, and revocation discipline across their lifecycle. | |
| Recommendation — Rotate emergency credentials immediately after use and store them in controlled secret management. Restrict break glass access to narrowly defined emergency actions and separate it from normal admin roles. Recertify emergency accounts regularly and revoke or reissue access after each activation. | ||
| CIS Controls v8 | 6 — Access Control Management | Break glass accounts are privileged access paths that require strict restriction and review. |
| 8 — Audit Log Management | Emergency use must be fully logged for accountability and review. | |
| 5 — Account Management | Emergency accounts need ownership, lifecycle control, and timely deprovisioning. | |
| Recommendation — Limit emergency accounts to approved use cases and remove unnecessary access paths. Log every activation, action, and deactivation event for break glass access. Assign owners, test credentials, and retire unused emergency accounts promptly. | ||
| NIST Zero Trust (SP 800-207) | 3 — Session and Device Trust | Break glass access should not be implicitly trusted just because it is emergency access. |
| 5 — Least Privilege Access | The core design principle for break glass accounts is minimal necessary privilege. | |
| Recommendation — Require strong authentication and continuous session visibility before granting emergency access. Scope emergency access to the smallest set of actions needed for recovery. | ||
| NIST CSF 2.0 | PR.AA — Identity Management, Authentication and Access Control | Break glass accounts are an identity and access control problem across clouds. |
| DE.CM — Continuous Monitoring | Emergency access only remains safe when activity is continuously monitored and reviewable. | |
| Recommendation — Enforce strong authentication and tightly governed access for emergency accounts. Monitor emergency account use and alert on any unscheduled or unusual activation. | ||
Practitioner Guidance
What to prioritise: Treat each cloud’s emergency path as a separate control object, even if the policy is global. The control should be easy to invoke during outage conditions, but difficult to confuse with everyday administration.
What to verify: Confirm that every break glass account has a named owner, a tested activation procedure, a rotation step after use, and monitoring that can reconstruct the session. If any one of those is missing, the account is not ready for real emergency use.
Decision rule: If the account can access production control planes without time bounds or post-use reissuance, treat it as standing privilege and reduce its scope before relying on it.
Practitioner takeaway: The goal is not to eliminate emergency access, it is to make emergency access provably temporary, tightly scoped, and fully attributable across every cloud it can reach.
