Runtime credential delivery is the practice of issuing access only when a workflow needs it, then removing it once the task is complete. For non-human identities, this reduces the lifespan of secrets and narrows the window in which exposed credentials can be abused.
Expanded Definition
Runtime credential delivery is a control pattern for non-human identities in which access is issued only at the moment a workflow needs it, then withdrawn when the task ends. It is most often implemented with ephemeral credentials, short-lived tokens, or just-in-time access brokers rather than long-lived shared secrets. In NHI programs, this approach narrows the abuse window and reduces the persistence of credentials across builds, jobs, services, and agents.
Definitions vary across vendors, but the operational goal is consistent: a workload should receive only the minimum credential it needs, for the shortest practical time, and only through a trusted delivery path. That makes the concept closely related to the principles described in the OWASP Non-Human Identity Top 10 and the broader identity assurance concepts in NIST SP 800-63 Digital Identity Guidelines, even though those standards do not define one single runtime-delivery mechanism.
For NHI Management Group, runtime delivery is best understood as a secret-lifecycle discipline, not merely a secret-rotation tactic. The most common misapplication is treating a short-lived secret as safe while still distributing it through persistent stores, which occurs when delivery is dynamic but retrieval paths remain static.
Examples and Use Cases
Implementing runtime credential delivery rigorously often introduces orchestration overhead, requiring organisations to weigh reduced secret exposure against more complex automation and dependency management.
- A CI/CD pipeline requests a cloud token only for the duration of a deployment job, then the token expires automatically when the job finishes.
- An AI agent receives a scoped API key at task start, uses it to query a tool, and relinquishes access before moving to the next workflow step.
- A containerized service fetches database credentials from a broker at startup, with the secret never written to a long-lived config file.
- A privileged maintenance task uses just-in-time access for a fixed window instead of keeping a standing credential on the host.
- A multi-cloud workload uses a federation flow so it can obtain credentials from the target environment at runtime rather than storing copied secrets locally, a pattern discussed in the Ultimate Guide to NHIs — Static vs Dynamic Secrets.
These patterns show up repeatedly in incident reporting, especially where secret sprawl and pipeline compromise are involved. The CI/CD pipeline exploitation case study illustrates why persistent secrets in automation paths are so dangerous, while the same runtime-delivery logic aligns with the short-lived credentialing models discussed in the OWASP Non-Human Identity Top 10.
Why It Matters in NHI Security
Runtime credential delivery matters because most NHI compromise paths depend on finding a credential that is valid long enough to reuse. NHIMG research shows that when AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and sometimes within 9 minutes, which leaves very little room for long-lived secrets to remain safe once discovered. That is why dynamic delivery is not just convenient engineering, but an attack-surface reduction measure.
It also addresses a major maturity gap in the field. In the 2024 Non-Human Identity Security Report by Aembit, only 19.6% of security professionals said they were strongly confident in their ability to securely manage non-human workload identities, and 59.8% saw value in dynamic ephemeral credentials. Runtime delivery directly answers that gap by shrinking exposure, limiting lateral movement, and making stolen secrets less reusable.
Organisations typically encounter the operational necessity of runtime credential delivery only after a secret leak, pipeline compromise, or AI workload abuse makes static credentials too risky to keep in circulation.
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 SP 800-63 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-02 | Covers improper secret handling and the need for short-lived, tightly controlled NHI credentials. |
| NIST SP 800-63 | AAL2 | Identity assurance concepts support stronger, time-bounded credential issuance for workload access. |
| NIST Zero Trust (SP 800-207) | PA/continuous verification | Zero Trust assumes short-lived access and verifies each request before granting credentials. |
Replace standing secrets with ephemeral delivery and verify every workflow gets only the access it needs.
