TL;DR: Machine identities often stall governance when a single owner is absent, changes roles, or leaves, creating orphaned access, delayed certifications, and audit risk, according to SailPoint. Shared ownership and succession planning turn machine identity governance into a continuous process instead of a person-dependent one.
Editorial analysis by NHI Mgmt Group, based on content published by SailPoint: “Machine identities don't take PTO, but their owners do: Why shared ownership and succession planning are critical”.
Key questions
Q: What breaks when machine identities have no clear owner?
A: When machine identities have no clear owner, offboarding, remediation, and accountability all fail together.
Q: Why do machine identities need succession planning?
A: Machine identities outlive role changes, holidays, and employee departures, so ownership must transfer without delay.
Q: How do teams know whether machine identity controls are actually working?
A: Look for complete inventory coverage, clear ownership, regular credential rotation, and the ability to revoke access quickly without breaking dependent services.
Practitioner guidance
- Map alternate owners for critical machine identities Assign at least two accountable humans to each high-value service account, bot, or grouped machine identity so approvals and certifications continue during absences.
- Embed ownership transfer into offboarding Require ownership reassignment before a staff mover or leaver is removed from the operating model, so no machine identity is left without a decision-maker.
- Review orphaned account exceptions regularly Create a recurring exception queue for machine identities with missing or inactive owners and route them for immediate remediation.
Bottom line: Machine identities become harder to govern when ownership is tied to one person and no backup path exists.

Shared ownership is now a governance control, not a convenience. Machine identities do not create accountability on their own, so the governance model has to assign it. A single owner creates a brittle control path that fails under leave, role change, or exit. The practitioner conclusion is simple: ownership redundancy belongs in the control design, not in informal backup habits.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should IAM teams handle ownership for service accounts and bots?
A: They should treat ownership as a lifecycle control, not a directory field. Every critical machine identity needs a named owner, an alternate owner, and a documented transfer path so reviews and approvals continue through leave, role changes, and exits. That keeps governance continuous and reduces orphaned-account risk.
