Agent Identity
Agent identity means giving an AI agent its own verifiable identity, so other systems can authenticate it, limit what it is allowed to do, and log its actions separately from the person it acts for.
In depth
Agent identity means giving an AI agent its own verifiable identity, so other systems can authenticate it, limit what it is allowed to do, and log its actions separately from the person it acts for. Without one, agents usually borrow a user's credentials or a shared API key. That makes permissions too broad and audit logs unclear. A 2025 OpenID Foundation whitepaper names agent identities and delegated authority as core open problems, building on OAuth-based protocols like MCP.
