Artificial intelligence agent identity lets systems distinguish one agent from another and connect actions to an accountable principal. It may include a stable identifier, cryptographic key, owner, role, runtime instance, and signed messages. Identity is the foundation for authentication, authorization, and reliable audit trails.
A display name alone is not sufficient because it can be copied. Strong identity mechanisms verify signatures and bind credentials to scoped permissions and expiry. In multi-agent systems, identity also helps recipients judge message provenance and prevents an unauthorized process from impersonating a trusted coordinator.

Frequently asked questions
How can an artificial intelligence agent prove its identity?
It can sign messages with a protected cryptographic key whose public identity is bound to an owner, role, runtime, and permitted scope.
Why is agent identity important in a multi-agent system?
It supports access control, message provenance, accountability, and investigation when many agents act through shared tools or communication channels.
