A temporary identity is a short-lived account or token-based session created for a narrow administrative task. In secure setup workflows, it limits what the user can do, expires after use, and reduces the risk of orphaned accounts or lingering access after configuration is complete.
Expanded Definition
Temporary identity is a narrow-scope, short-lived identity used to complete a specific administrative action, then expire automatically or be revoked immediately after use. In NHI and IAM practice, it sits between full standing access and one-off manual intervention, supporting workflows where a user or operator needs elevated access without inheriting a durable account.
Definitions vary across vendors and internal policies. Some teams treat a temporary identity as a just-in-time account, while others include ephemeral tokens, break-glass sessions, or task-scoped service credentials. The key distinction is not the naming convention but the control objective: limit privilege duration, constrain the action set, and reduce residual access. That makes it closely related to least privilege, session controls, and Zero Trust patterns described in the NIST Cybersecurity Framework 2.0.
In NHI governance, temporary identity should be designed as a lifecycle state with issuance, approval, use, expiration, and auditability rather than as an ad hoc shortcut. The most common misapplication is treating a temporary identity like a permanent admin account with a short password timer, which occurs when access is created without automatic expiry, scope limits, or post-use revocation.
Examples and Use Cases
Implementing temporary identity rigorously often introduces workflow friction, requiring organisations to balance faster remediation or deployment against tighter approval, logging, and expiry enforcement.
- A platform engineer receives a time-boxed identity to rotate certificates on a production cluster, then the identity is removed once the task completes.
- A vendor support session is granted a temporary identity with read-only access to a single system during incident triage, instead of sharing a standing service account.
- An automation pipeline issues an ephemeral identity for a one-time infrastructure migration, reducing the chance of lingering credentials in build logs or config files.
- A break-glass workflow creates a temporary identity for emergency admin access, but only after approval and with enhanced logging for later review.
These patterns are especially relevant when teams are reducing secret sprawl, which the Ultimate Guide to NHIs shows remains a persistent issue across organisations. They also align with identity assurance thinking in the NIST ecosystem, where session scope and lifecycle discipline matter as much as initial authentication.

Why It Matters in NHI Security
Temporary identity matters because many NHI incidents begin with access that was meant to disappear but did not. A short-lived identity can sharply reduce blast radius, but only if expiry, revocation, and observability are enforced across the full workflow. Without that, temporary access becomes another durable credential path hidden behind administrative convenience.
NHI Mgmt Group data shows that only 20% of organisations have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, which illustrates how often short-lived access turns into lingering access. That risk is amplified when temporary identities are created in tooling, CI/CD, or incident response flows without central oversight. The Top 10 NHI Issues and the broader guidance in the Ultimate Guide to NHIs both highlight how identity sprawl, excessive privilege, and weak lifecycle management drive exposure.
Practitioners should treat temporary identity as a governance control, not a convenience feature: every issuance needs ownership, expiry, and evidence of removal. Organisations typically encounter the consequences only after a support session, migration, or emergency access path is abused, at which point temporary identity becomes operationally unavoidable to address.
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 and OWASP Agentic AI Top 10 address the attack and risk surface, while NIST CSF 2.0, NIST Zero Trust (SP 800-207) and NIST SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 | Temporary identities must not leave behind reusable secrets or standing access. |
| NIST CSF 2.0 | PR.AC-4 | Least privilege and access lifecycle control are core to temporary identity use. |
| NIST Zero Trust (SP 800-207) | ID, JIT access patterns | Zero Trust supports ephemeral, continuously verified access instead of standing privilege. |
| NIST SP 800-63 | AAL2 | Short-lived access should still be bound to appropriate authenticator assurance. |
| OWASP Agentic AI Top 10 | A-03 | Agentic workflows often need ephemeral credentials and constrained execution authority. |
Grant temporary identities only with explicit verification, narrow scope, and short duration.
