Identity and security teams should own the control design, while HR and IT should align on timing and verification. The ownership question matters because onboarding secrets are not just operational tasks; they are part of joiner lifecycle governance and should be treated like any other access decision.
Why This Matters for Security Teams
Onboarding secret delivery is not a clerical handoff. It defines who can create, approve, transport, and later revoke the credentials that let new workloads, service accounts, and tools operate. If ownership is vague, secrets tend to spread into tickets, chat threads, and code, which is exactly how lifecycle control breaks down. NHIMG research shows 62% of all secrets are duplicated and stored in multiple locations, and only 20% of organisations have formal processes for offboarding and revoking API keys, a warning sign that joiner controls are often weaker than teams assume in production. That is why ownership should sit with identity and security, with HR and IT providing timing, employment status, and system readiness signals. Guidance aligned to NHI Lifecycle Management Guide and the OWASP Non-Human Identity Top 10 treats secret delivery as an access decision, not a convenience task. In practice, many security teams encounter secret sprawl only after a joiner credential has already been copied into places it cannot be reliably recovered from.
How It Works in Practice
A workable model separates responsibility by control point. Identity security owns policy, templates, approval rules, storage standards, and revocation logic. Platform or IT teams integrate delivery into onboarding workflows. HR supplies the employment trigger, and the application owner confirms the need for the secret. For higher-risk systems, current guidance suggests using just-in-time issuance, short TTLs, and workload identity rather than handing out a long-lived static secret at join time. That means the secret exists only long enough for the workload to authenticate, perform its task, and then expire or rotate automatically.
Operationally, this usually includes:
- pre-approved onboarding patterns for standard workloads, so teams do not improvise delivery paths
- vault-backed issuance with audit logging, not email, chat, or ticket attachments
- owner assignment for each secret, including rotation and revocation duties
- verification that the receiving workload can authenticate through workload identity before any standing credential is issued
NHIMG research on Guide to the Secret Sprawl Challenge and Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs shows why this matters: secrets stored outside dedicated managers and weak lifecycle processes are common failure points. For implementation principles, the OWASP Non-Human Identity Top 10 and the governance patterns in the Top 10 NHI Issues both point to the same operational truth: delivery and lifecycle control need one accountable owner, even when many teams touch the process. These controls tend to break down when onboarding is fully self-service across many application teams because approval, delivery, and revocation then fragment across inconsistent local workflows.
Common Variations and Edge Cases
Tighter onboarding control often increases delivery friction, so organisations must balance speed against the risk of uncontrolled secret proliferation. That tradeoff becomes sharper for regulated environments, acquisitions, and highly decentralised engineering teams. There is no universal standard for this yet, but current guidance generally favours a central policy owner with distributed execution, rather than allowing each team to invent its own onboarding secret path.
A few edge cases matter:
- For ephemeral workloads, a static secret may be the wrong control entirely, because workload identity and JIT provisioning reduce the need for standing credentials.
- For third-party or vendor onboarding, security should own the approval model, while procurement or platform teams verify contractual timing and technical readiness.
- For emergency access, break-glass procedures should be documented separately from normal joiner onboarding, with explicit expiration and post-use review.
The best comparison point is not human onboarding, but lifecycle governance for machine identities, where ownership must extend through issuance, use, rotation, and retirement. That is why Guide to NHI Rotation Challenges and CI/CD pipeline exploitation case study are relevant reading: they show how quickly onboarding mistakes become persistence problems when secrets are not rotated or revoked cleanly. The practical rule is simple: if a team can create a credential, it must also be able to prove who owns its end-of-life. That model gets harder in legacy systems that cannot issue short-lived credentials or support centralized revocation.
