Locally Managed Account

A locally managed account is an application or system account that is not governed by the organisation’s central identity provider. These accounts often appear in shadow IT, standalone SaaS tools, or legacy integrations. They are important because they can bypass SSO controls, MFA reporting, and centralized audit processes.

Expanded Definition

A locally managed account is a system or application account whose credentials, lifecycle, and access decisions are controlled outside the organisation’s central identity provider. In practice, that means the account may exist on a server, in a SaaS tenant, or inside a legacy integration without being subject to the same joiner, mover, leaver, and reporting processes as centrally governed identities.

The key boundary is governance, not just location. A local account can be legitimate and necessary, especially for break-glass access, device-specific administration, or software that cannot federate. The security problem appears when local accounts become the default because they are easier to create than to integrate. That is where definitions vary across vendors and environments: some teams treat any non-federated account as “local,” while others reserve the term for accounts managed directly on the target system.

For readers comparing this with service account, the distinction is practical. A service account may be centrally managed or local; the locally managed part is what removes it from standard identity controls. See Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs for the lifecycle lens that this term often falls outside.

Examples and Use Cases

• A legacy payroll system uses a shared administrator login stored on the host because it cannot integrate with SSO. The account is local to the application and must be tracked separately from directory identities.
• A standalone SaaS tool creates its own native users for automation jobs. These accounts may support business continuity, but they often escape central access reviews unless the owner records them explicitly.
• A network appliance keeps a local emergency account for recovery when the directory is unavailable. This is a valid use case, but it needs tightly controlled credentials and clear ownership.
• A contractor portal or shadow IT tool introduces local accounts because the product was adopted before governance review. That tradeoff usually buys speed at the cost of weaker visibility and weaker deprovisioning.
• A CI/CD integration uses a locally managed technical account to push updates into a target system. The account can be necessary, but the team must still decide whether it is monitored, rotated, and documented like other privileged access.

Where local accounts proliferate, the tradeoff is usually convenience versus assurance. The more autonomy the target system has over identity, the more important it becomes to inventory the account outside the system itself.

Security Implications

Locally managed accounts weaken central control assumptions because they can bypass SSO policy, inconsistent MFA enforcement, and directory-based audit trails. They are also easy to forget during offboarding, vendor change, or system retirement, which creates long-lived access paths that still look legitimate to the host system.

The common failure mode is drift: one team creates the account for a quick fix, another inherits the system later, and no one can say with confidence who owns the credential or when it was last reviewed. That produces hidden privilege, stale access, and unclear accountability. NHIMG research shows that only 5.7% of organisations have full visibility into their service accounts, which illustrates how quickly non-centralised accounts can escape oversight.

Operationally, the symptoms are predictable: missing MFA logs, incomplete access reviews, credentials shared across admins, and accounts that survive long after their original purpose. In a compromise, the blast radius can be larger than expected because locally managed accounts often have direct system access without the friction that central identity controls would otherwise impose. Top 10 NHI Issues is a useful companion perspective when local accounts are part of a broader machine-identity problem.

Domain and Governance Relevance

In NHI governance, locally managed accounts matter because they are a common path by which machine identities, automation accounts, and embedded credentials fall outside the identity lifecycle. That changes how ownership is assigned: the business system owner, platform team, and security team may each assume someone else is managing the account.

This term is especially relevant when organisations rely on hybrid estates, third-party SaaS, or legacy systems that cannot join central identity workflows. The governance question is not whether every account must be federated, but whether exceptions are explicitly registered, reviewed, and retired on a defined schedule. Without that discipline, local accounts become a parallel identity plane.

For NHI programs, the practical implication is that local accounts should be treated as inventory items with lifecycle obligations, not as incidental configuration details. They need the same attention to ownership, revocation, and evidence as other non-human identities, especially when they hold administrative or integration privileges. The NHI Lifecycle Management Guide is directly relevant to that governance lens.

Risk and Threat Considerations

Locally managed accounts create material exposure because they sit outside central identity controls that normally help enforce least privilege, MFA consistency, logging, and rapid revocation. They are attractive to attackers precisely because they can persist unnoticed in legacy systems, administrative consoles, and third-party platforms.

Failure mechanism: The risk materialises when an account is created for convenience, then never rotated, monitored, or deprovisioned through a central process. Compromise can occur through weak passwords, reused secrets, exposed configuration, or inherited admin access, and defenders may miss the activity because the account does not generate the same identity telemetry as federated access.

Impact: A compromised local account can provide durable access to systems that contain sensitive data, administrative functions, or automation pathways. It can also undermine incident response because responders may not have a complete view of where the account exists or which services trust it.

Practitioner Guidance

What to watch for: The main signal is any account that exists only inside a target system and cannot be governed through your normal identity workflow. That is often the point where ownership, review cadence, and revocation responsibilities become ambiguous.

Governance implication: Treat locally managed accounts as exceptions that require explicit registration and review, not as invisible technical shortcuts. If a system must keep them, the organisation should know who owns them, why they exist, and how they are removed when no longer needed.
