An account created directly inside an application rather than governed through a central identity provider. Local accounts often escape enterprise lifecycle controls, which makes them harder to review, secure, and retire consistently across cloud and SaaS environments.
Expanded Definition
A local account is an identity created and authenticated inside a single application, server, or SaaS platform rather than brokered by a central identity provider. In NHI operations, that distinction matters because the account lifecycle, approval path, and revocation process may sit outside enterprise governance. Definitions vary across vendors, but the security issue is consistent: local accounts can become durable exceptions that bypass federation, central logging, and standard offboarding. That makes them especially risky when used for admin access, automation, or emergency break-glass access without compensating controls. A local account is not inherently insecure, but it becomes difficult to justify when the same access could be managed through federated identity, PAM, or Zero Trust controls aligned to the NIST Cybersecurity Framework 2.0. The practical question is whether the account is temporary, reviewed, and traceable, or simply lingering as a permanent exception. The most common misapplication is treating a local account as a harmless convenience, which occurs when teams create it for urgent access and never bring it back under formal review.
Examples and Use Cases
Implementing local account governance rigorously often introduces operational friction, requiring organisations to weigh recovery speed against the cost of exception handling and periodic review.
- A database admin account exists only inside a SaaS console, used because the platform cannot yet integrate cleanly with the corporate IdP. That account must still be inventoried, owned, and rotated as part of the broader NHI lifecycle described in the Ultimate Guide to NHIs.
- An emergency break-glass account is stored locally on a production system so operators can recover access during IdP outage events. This is a legitimate use case, but it needs tight approval, monitoring, and documented reset procedures consistent with NIST Cybersecurity Framework 2.0.
- A legacy application still relies on app-internal usernames and passwords because federation was never implemented. Security teams often leave this unchanged too long, even though the same account would benefit from the lifecycle and visibility practices discussed in the Ultimate Guide to NHIs.
- An RPA or automation tool uses a local service account to run scheduled jobs. If that account is not tied to a clear owner and rotation plan, it can outlive the workflow it supports.
- A third-party managed application creates its own administrator account for support access. That can be acceptable for availability, but only if the access path is time-bound and reviewed against enterprise policy.
Why It Matters in NHI Security
Local accounts matter because they frequently become blind spots in the NHI estate. They do not always appear in the IdP, yet they can still hold privileged access, secrets, or operational control over critical systems. That means they often escape the reviews used for federated identities, which is exactly how long-lived exceptions accumulate. NHI visibility is often far weaker than leaders expect; NHI Mgmt Group reports that only 5.7% of organisations have full visibility into their service accounts in the Ultimate Guide to NHIs. The same governance gap applies to local accounts when ownership, rotation, and retirement are not enforced. Under Zero Trust Architecture, every account should be continuously validated, and local accounts are no exception, which is why NIST Cybersecurity Framework 2.0 remains relevant here. For NHI programmes, the main risk is not just the existence of the account but the lack of a control plane around it. Organisations typically encounter the consequence only after an audit failure, breach investigation, or service outage, at which point the local account becomes operationally unavoidable to address.
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 Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 | Local accounts often bypass centralized lifecycle and secret controls. |
| NIST CSF 2.0 | PR.AC-1 | Access is governed through identity management and approved credentials. |
| NIST Zero Trust (SP 800-207) | Zero Trust assumes no implicit trust for any account, including local ones. |
Inventory local accounts, assign owners, and rotate or retire them on a fixed schedule.
