TL;DR: Access keys are dynamic identity credentials, not encryption keys, and treating them the same creates visibility, rotation and zero-trust failures that increase breach risk, according to Aembit and supporting breach research. The real issue is not credential storage, but whether access is issued, scoped and revoked as runtime identity rather than static secret material.
Editorial analysis by NHI Mgmt Group, based on content published by Aembit: “Managing Encryption Keys vs. Access Keys”.
By the numbers:
- Stolen credentials were implicated in 22% of breaches in Verizon’s 2025 DBIR, showing how often access credentials become the initial foothold.
- GitGuardian reports that 64% of secrets exposed in 2022 were still valid four years later, which shows how long-lived access credentials can persist when managed poorly.
- Attackers probe exposed AWS credentials in under 17 minutes, leaving very little time to detect and revoke leaked access keys.
Key questions
Q: What breaks when users manage their own encryption keys?
A: What breaks is the lifecycle.
Q: Why do short-lived credentials reduce risk for workloads and privileged access?
A: Short-lived credentials reduce risk because they shrink the window in which a stolen secret can be reused and limit the value of persistent access.
Q: What are the signs that access governance is failing in practice?
A: The clearest signs are slow remediation, repeated rubber stamp access reviews, and missed permissions outside traditional HR linked systems.
Practitioner guidance
- Separate access keys from encryption-key governance Inventory which credentials authenticate runtime access versus which keys protect data, then assign different lifecycle, rotation and audit controls to each class.
- Replace long-lived access keys with runtime issuance For workloads, APIs and CI/CD pipelines, issue short-lived credentials at the moment of use and revoke them when the session or task ends.
- Track where machine credentials actually live Map keys in source code, environment variables, containers, secret stores and build pipelines so hidden access does not escape inventory and review.
Bottom line: Access keys and encryption keys have different security jobs, so managing them with the same policy creates avoidable governance gaps.

Access keys are an identity problem, not a storage problem: The article’s central insight is that runtime credentials fail when they are governed like encryption material. That framing matters because access keys authorize action, they do not merely protect data. For IAM and NHI programmes, the practical conclusion is that lifecycle and issuance controls must be designed around usage context, not vault custody.
A question worth separating out:
Q: Should organisations manage access keys and encryption keys separately?
A: Yes. Encryption keys protect data and usually belong in centralised cryptographic controls, while access keys authorise workloads and need runtime issuance, scoped permissions and tighter lifecycle visibility. Combining them under one policy hides the different failure modes and weakens governance. Separate controls make it easier to see which problem you are actually solving.
