Service Account

A service account is an identity entity in cloud platforms used by non-human workloads, typically bound to a set of IAM permissions and valid for a long period.

The service account model has structural flaws in agent scenarios: an agent's behavior is dynamically generated, and its call sequences cannot be fully enumerated at the provisioning stage; orchestration-type agents also need to act on behalf of downstream users, inherently requiring broader permissions.

Connection Sharing is suitable for service-account-style integrations, where a bot or automated process operates under a unified identity rather than impersonating a specific user.

A service account is a non-personified account identity, typically used for applications, bots or automation scripts rather than a specific human user.

Using service accounts can prevent integration interruptions caused by employee departures or role changes.

In multi-tenant agent systems, credential isolation is typically implemented through three approaches: delegated authorization, service accounts with scope mapping, and credential vaults.

A service account is an independent identity created specifically for automated tasks, whose permissions can be configured independently, revoked at any time, and are not tied to personal login credentials.

When multiple agents share the same service account, permissions are in effect superimposed, and the permission boundary of any single agent cannot be defined.

Traditional IAM systems are designed around human users and static service accounts, with service account permissions statically pre-configured.

The fundamental difference between AI Agents and service accounts is that Agents act on behalf of specific users and their permissions should change dynamically with user identity, whereas service account permissions are preset and unrelated to any specific user.
