Administrators should set the default based on the organisation’s application landscape, user maturity, and policy goals. If most target systems still require traditional passwords, a password default may be more practical. If passphrases are widely accepted, they can improve usability without weakening control, provided policy enforcement remains consistent.
Why This Matters for Security Teams
The default secret generation method is not a cosmetic setting. It shapes how users create credentials, how easily systems accept them, and whether policy can be enforced consistently across a real application estate. If the default is too weak, teams inherit avoidable password reuse and poor entropy. If it is too strict for the environment, users bypass the control or store secrets unsafely. NHI Management Group’s Guide to the Secret Sprawl Challenge shows why weak defaults often become operational debt, especially when secrets are created faster than governance can keep up.
This is a governance decision, not an end-user preference. Administrators need to weigh application compatibility, identity assurance expectations, and the policy outcomes the organisation is trying to achieve. The right default for a mature SSO-driven environment may differ from the right default for a mixed estate that still depends on legacy password flows. Current guidance suggests treating the default as a control decision aligned to risk, not as a convenience feature. In practice, many teams discover the default was wrong only after secrets have already been distributed across systems and remediation becomes expensive.
How It Works in Practice
Administrators should define the default generation method centrally, then enforce it through the password management workflow rather than leaving it to individual users. The key question is not “what is easiest to type,” but “what will be accepted everywhere the secret must work.” A password default may be practical when target systems enforce legacy constraints, while passphrases may be preferable when length is supported and user education is strong. The policy should also define minimum length, entropy expectations, character set handling, and whether generated values must be unique per system.
Practitioners should anchor this choice in documented governance and lifecycle controls. The Ultimate Guide to NHIs and the NHI Lifecycle Management Guide both emphasise that secret creation, rotation, and revocation should be treated as part of a managed lifecycle. For baseline security expectations, align the configuration to the NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10, especially where generated secrets may be reused by service accounts, API keys, or automation tools.
- Use administrator-managed defaults so generation is consistent across teams and business units.
- Choose password generation when compatibility matters more than memorability.
- Choose passphrases when the target system supports them and policy can enforce adequate length.
- Review the default again when application support changes, not only during annual policy review.
Where this breaks down is in mixed estates with older applications that silently reject long or symbol-rich values, because the policy can be correct while the downstream integration still fails.
Common Variations and Edge Cases
Tighter secret generation defaults often improve security but increase help desk friction, onboarding time, and integration work, so organisations need to balance assurance against compatibility. That tradeoff is especially visible when different application classes coexist under one password management system.
Some environments can standardise on passphrases for human use while still issuing random passwords or tokens for service workflows. That is often the better split because human-entered secrets and machine-managed secrets have different usability constraints. For high-risk environments, current guidance suggests pairing the default with strong policy enforcement, secret rotation, and vaulting, rather than relying on the generation format alone. The Top 10 NHI Issues and the Guide to the Secret Sprawl Challenge both reinforce that weak handling around creation and storage often matters more than the label on the generator.
There is no universal standard for this yet. The practical choice depends on application constraints, user maturity, and whether the organisation is trying to reduce cognitive load or maximise credential strength. In legacy-heavy environments, password generation remains the safer operational default because it is more likely to work everywhere.
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 CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0, NIST SP 800-53 Rev 5 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Addresses secure creation and management of non-human secrets. |
| NIST CSF 2.0 | PR.AC-1 | Default secret settings affect how access is established and governed. |
| NIST SP 800-53 Rev 5 | IA-5 | Covers authenticator management, including generated secret quality and lifecycle. |
| CSA MAESTRO | A1 | Agentic and automated workflows need governed credential issuance. |
| NIST AI RMF | Governance of automated decision-making should cover credential defaults. |
Set a central generation default and enforce unique, high-entropy secrets across all NHI workflows.
