They should do both, but incomplete lifecycle management can erase the value of MFA over time. If orphaned accounts, stale keys, and undocumented exceptions remain in place, strong authentication only protects a subset of the real risk. The best sequence is to secure the highest-risk access paths first while building the ownership and review process that keeps them governed.
Why This Matters for Security Teams
MFA rollout and lifecycle management are not competing projects; they protect different failure modes. MFA helps when a credential is stolen or guessed, but lifecycle control determines whether that credential should still exist, who owns it, and whether it is still attached to a live workload. In NHI estates, that distinction matters because stale accounts, duplicated secrets, and undocumented exceptions quietly widen the attack surface even when authentication is strong.
The risk is often visible in the numbers: the Ultimate Guide to NHIs notes that 97% of NHIs carry excessive privileges, and only 20% of organisations have formal offboarding and API key revocation processes. If access is not retired when a service is decommissioned, the best MFA policy still leaves a usable path for abuse. That is why current guidance from NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 both point toward governance, inventory, and continuous control validation rather than one-time authentication projects.
In practice, many security teams discover the gap only after a dormant API key, orphaned service account, or forgotten CI/CD secret has already been reused somewhere it should never have remained active.
How It Works in Practice
The practical sequence is to secure the most exposed access paths first while building the lifecycle controls that keep those paths governed over time. That means identifying which NHIs touch production data, external integrations, privileged automation, and cloud control planes, then enforcing MFA or stronger challenge controls where human approval is part of the flow. For machine-to-machine access, the stronger pattern is usually not MFA in the human sense, but short-lived credentials, workload identity, and tightly scoped authorization that can be revoked automatically.
Lifecycle management supplies the missing backbone: ownership, approval, inventory, rotation, offboarding, and exception review. The NHI Lifecycle Management Guide and the Guide to the Secret Sprawl Challenge both reinforce that secrets multiply across code, tickets, vaults, and pipelines unless there is a single accountable process. In parallel, control design should follow OWASP Non-Human Identity Top 10 guidance: inventory the identity, reduce privilege, shorten credential lifetime, and verify whether the access path still serves a current business purpose.
- Start with the highest-risk NHIs, not the easiest ones.
- Use MFA where a person is still in the approval loop.
- Use JIT access, short TTL secrets, and revocation for autonomous or service-driven access.
- Track ownership so every identity has a retire-or-renew decision.
That approach aligns with NIST Cybersecurity Framework 2.0 and helps reduce the conditions behind exposed tokens and stale credentials, including the 91% of former employee tokens that remain active after offboarding, as reported by The 2025 State of NHIs and Secrets in Cybersecurity. These controls tend to break down in highly distributed engineering environments because ownership is fragmented across platform, app, and DevOps teams.
Common Variations and Edge Cases
Tighter authentication often increases operational overhead, requiring organisations to balance stronger assurance against automation speed and release friction. There is no universal standard for this yet, especially where service accounts, CI/CD jobs, and autonomous agents need non-interactive access. In those environments, lifecycle management usually matters more than MFA because the key question is not just “who authenticated?” but “should this identity still exist, and what can it do right now?”
That is where the exception handling gets tricky. Some workflows still benefit from step-up approval, such as production break-glass actions or sensitive admin consoles. Others should move toward Zero Standing Privilege, JIT issuance, and policy-based revocation rather than static long-lived credentials. NHI programs that rely on “set and forget” MFA tend to miss the real problem: secrets that live too long, permissions that never shrink, and service identities that survive beyond the systems they support. The Top 10 NHI Issues and Guide to NHI Rotation Challenges both show why rotation and offboarding remain fragile without explicit ownership. For audit and governance teams, the Ultimate Guide to NHIs — Regulatory and Audit Perspectives is especially useful when proving that access was both authenticated and justified.
The practical rule is simple: use MFA to harden valid access, but use lifecycle management to prevent invalid access from lingering. When teams skip that second half, the environment stays permissive even if every login is challenged.
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 address the attack and risk surface, while NIST CSF 2.0 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-03 | Rotation and revocation are central to preventing stale NHI access. |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege access control supports governed rollout of MFA and lifecycle controls. |
| NIST AI RMF | Governance and accountability are needed to keep autonomous access paths controlled. |
Assign accountable owners and policy checks for every non-human identity and exception.
