TL;DR: Local files cannot provide the source of truth, access control, or audit trail production systems require, according to Doppler analysis of .env-based workflows. For practitioners, the issue is not convenience but whether secrets remain governable as environments and services multiply.
Editorial analysis by NHI Mgmt Group, based on content published by Doppler: “Secrets management best practices: From .env files to centralized control”.
Key questions
Q: How should security teams prevent secrets from reaching shared Git repositories?
A: Use a two-layer approach.
Q: What is the difference between dynamic secrets and static secrets in operational access control?
A: Dynamic secrets are issued for a limited time and are meant to expire after a task or session ends, which reduces the window of misuse.
Q: How do service accounts rotate secrets without breaking production access?
A: Service accounts rotate secrets without breaking production by using overlapping validity, staged rollout, and dependency inventory.
Practitioner guidance
- Centralise production secrets Move authoritative values into a dedicated secrets manager and inject them dynamically into local, staging, and production environments from that source.
- Scope access by service identity Map each secret to the exact service or workload that needs it, and remove broad team or environment-based read permissions.
- Automate rotation with revocation Generate a new value, roll it out to consumers, and revoke the old credential so the previous value cannot still be used.
Bottom line: .env files are useful for local configuration but fail as soon as production needs consistent access control, rotation, and audit evidence.

Secrets sprawl is the control failure, not the side effect. Once credentials exist in multiple files, environments, and deployment paths, the organisation has already lost the single source of truth that secrets governance depends on. That loss makes rotation, revocation, and access review unreliable because no one can say with confidence which copy is authoritative. The practical conclusion is that the governance model, not the file format, is what has failed.
A few things that frame the scale:
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools, according to the Ultimate Guide to NHIs.
- 54% of organisations are dissatisfied with their current secrets management solution because not all secrets are secured, and 43% cite lack of central management, according to the 2024 State of Secrets Management Survey.
A question worth separating out:
Q: How should teams audit secret access for compliance?
A: Teams audit secret access by logging every read, use, and administrative change to secrets, then tying each event to an accountable identity and system. Review privileged access to vaults, key stores, and secret retrieval APIs, and reconcile access against approved ownership, JIT elevation, and rotation records. Separate human admin access from machine retrieval paths.
