Service Account
A machine identity designed for non-human subjects, commonly used in cloud platforms and operating systems. It is not bound to an individual and its credentials can be rotated.

When using a service account to access Google Sheets, you need to share the target spreadsheet with that service account's email address, otherwise the n8n node will return a 403 permission error.
Giving an AI feature a separate service account with broad read permissions creates a 'privileged path' that bypasses the product's permission system, and any request that can reach that interface may read records that the user should not be able to see.
Not knowing the Agent exists is the most common AI Agent security failure path, manifesting as failing to see that an Agent holds credentials it should not hold (such as service accounts, unapproved built-in tool permissions, or overly broad OAuth grants).
Service accounts are machine accounts for non-human identities, typically granted long-lived keys for service-to-service calls, and they are often over-privileged, difficult to rotate, and not bound to a specific person; once obtained by an Agent, they become a ghost identity with no MFA, no behavioral baseline, and the ability to lurk long-term.
The claim that AI agents are simply equivalent to service accounts is incorrect, as agents collect multiple credentials for legitimate reasons.
n8n's Google Sheets node creates credentials by clicking "Sign In with Google" and approving access permissions; once saved, the credentials can be reused by subsequent workflows.
In traditional identity management systems, the principals of a system are typically limited to two categories: human users and service accounts.
A service account is a non-interactive machine identity designed specifically for applications or automated processes, and is fundamentally different from a personal user account.
