Accountability should sit with the business owner who requested the access and the identity team that allowed it to persist without an expiry condition. When access is granted for a project or incident, the request must include a clear owner and end state. Without that, nobody owns the subtraction, so the permission becomes permanent by default.
Why This Matters for Security Teams
temporary access that never expires is not a minor housekeeping issue. It turns an approved exception into standing privilege, which defeats the point of time-bound access, incident scoping, and post-change cleanup. The ownership gap is usually the real failure: the business asks for access, identity grants it, and no one is clearly responsible for removing it when the task ends. NHI Management Group notes that only 20% of organisations have formal processes for offboarding and revoking API keys in the Ultimate Guide to NHIs.
That matters because permanent access often survives the original context. A project closes, an incident is resolved, or a vendor integration is retired, but the credential remains valid and callable. The risk is not just overpermissioning; it is accountability drift. The OWASP Non-Human Identity Top 10 frames this as a lifecycle failure, not a one-time provisioning issue. In practice, many security teams encounter lingering access only after an audit, a breach review, or a production incident exposes how long the exception quietly remained active.
How It Works in Practice
Accountability for temporary access should be explicit at request time and enforced at expiration time. The business owner should own the need, the end state, and the business justification. The identity or platform team should own the control mechanics, including expiry, revocation, and evidence that removal occurred. Best practice is evolving toward policy-driven access with automatic expiry, because manual follow-up does not scale across service accounts, API keys, and agent credentials.
For practical implementation, tie every temporary grant to a ticket, workflow, or approval object that includes:
- a named requestor and approver
- a specific use case or change window
- a hard expiration timestamp
- a revocation trigger for completion, rollback, or incident closure
- logging that proves the access was removed
Where possible, use just-in-time provisioning, short-lived tokens, and workload identity instead of long-lived static secrets. That reduces the chance that a forgotten credential remains usable after the task ends. The 52 NHI Breaches Analysis reinforces a recurring pattern: once a non-human credential escapes its intended lifecycle, it is often reused far beyond the original scope. Guidance from the OWASP NHI community and the OWASP Non-Human Identity Top 10 is clear that lifecycle control must be built into issuance, not bolted on after the fact. These controls tend to break down in highly distributed environments with many ad hoc owners because there is no reliable system of record for who should trigger revocation.
Common Variations and Edge Cases
Tighter temporary-access control often increases operational overhead, so organisations must balance speed against the cost of missing a clean removal. That tradeoff is especially visible during incidents, where teams want fast restoration but also need a clear end state once the emergency is over. Current guidance suggests using exception paths for break-glass access, but those paths still need ownership, expiry, and post-event review.
There is no universal standard for this yet across every toolchain, but the direction is consistent: shorten duration, reduce standing privilege, and make revocation observable. In agentic or automated environments, the problem is even harder because access may be issued to a workload rather than a person. In those cases, the accountable party is still the business owner for the use case, while the platform owner must ensure the credential cannot outlive the workflow. If a team cannot name who approves removal, the control has already failed.
Where third parties are involved, the risk of ownership gaps increases because vendors may assume the customer will revoke access while the customer assumes the vendor has already rotated it. The safest practice is a shared offboarding checklist with a single accountable owner and a mandatory expiry condition in the original request.
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 NIST CSF 2.0 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Addresses missing expiry and revocation controls for non-human credentials. |
| NIST CSF 2.0 | PR.AC-1 | Access provisioning and revocation map directly to accountable identity control. |
| NIST Zero Trust (SP 800-207) | ID | Zero Trust depends on bounded, continuously evaluated access rather than permanent exceptions. |
Require every temporary credential to carry a TTL and automate revocation at the end of the approved window.
