TL;DR: Secrets managers reduce plaintext exposure, but they do not govern context, behavior, or lifecycle for non-human identities, according to Token Security. In cloud and AI-heavy environments, that leaves standing privilege, secret sprawl, and orphaned credentials as the real control gaps, not vault encryption.
Editorial analysis by NHI Mgmt Group, based on content published by Token Security: “The Problem With Secrets-Only Approaches to Machine Access Security”.
Key questions
Q: What breaks when organisations keep permanent secrets for admin and machine access?
A: Permanent secrets weaken zero trust because they leave always-on credentials in places that are difficult to control and easy to reuse.
Q: Why do long-lived secrets create more risk for machine identities?
A: Long-lived secrets turn a one-time exposure into persistent access.
Q: What are the signs that secret governance is failing?
A: Common signs include secrets that never expire, weak rotation discipline, and inconsistent lifecycle management across vaults and applications.
Practitioner guidance
- Map every secret to its workload identity Link each API key, certificate, and token to the service, owner, and environment that actually uses it so the credential cannot be treated as anonymous access.
- Track credential copies outside the vault Scan pipelines, laptops, caches, environment variables, and logs for replicated secrets, then treat each copy as an independent exposure point until removed.
- Replace standing machine privilege with task-scoped access Issue short-lived permissions only for the specific action and revoke them when the task ends, especially for workloads that can act autonomously.
Bottom line: Secrets-only machine access protects storage but leaves the actual use of non-human credentials outside governance.

Secrets-only security is a storage control, not an identity control. The article correctly separates hiding a credential from governing the workload that uses it. That distinction matters because a bearer secret carries no intent, no ownership signal, and no runtime context. The implication is straightforward: machine access programmes that stop at vaulting are governing storage, not access.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Why do machine identities make secrets management harder than human access management?
A: Machine identities scale faster, change more often, and are frequently owned by applications rather than people. That makes ownership, rotation, and offboarding harder to standardise. When credentials outnumber human accounts, manual review breaks down and the organisation needs lifecycle controls that work for service accounts, tokens, and certificates.
