ZeroID - Open-Source Identity Platform for AI Agents

What Happened

ZeroID has launched an open-source identity platform designed specifically for autonomous agents and multi-agent systems. This platform addresses a significant issue in the realm of AI: attribution. As orchestrator agents spawn sub-agents to perform tasks, the need for clear identification and accountability becomes crucial. Traditional methods fall short, lacking the necessary traceability for actions taken by these agents.

The Attribution Problem

The core challenge that ZeroID tackles is the attribution problem in agentic workflows. When sub-agents execute tasks, they often call APIs, write files, or run shell commands without a clear trail of who authorized these actions. Existing solutions, such as shared service accounts, do not provide a delegation trail. Moreover, standard OAuth 2.0 and OIDC flows are not equipped to handle scenarios where agents operate asynchronously or cross organizational boundaries without human intervention.

How ZeroID Works

ZeroID implements RFC 8693 token exchange, which allows for the creation of verifiable delegation chains. This means that when an orchestrator delegates tasks to a sub-agent, the resulting token includes the identities of both the orchestrator and the sub-agent, along with the original authorizing principal. Importantly, permissions are automatically limited at each step, ensuring that sub-agents cannot access more than what the orchestrator has.

Revocation and Real-Time Access Evaluation

Another key feature of ZeroID is its integration with the OpenID Shared Signals Framework (SSF) and the Continuous Access Evaluation Profile (CAEP). This allows for real-time revocation of tokens. If a token is revoked at any point in the delegation chain, all downstream tokens derived from it are immediately invalidated. For scenarios where real-time checks are impractical, ZeroID offers local JWT verification against a cached JWKS endpoint, balancing latency with revocation immediacy.

Deployment and SDKs

ZeroID is designed to run as a containerized service, supported by a PostgreSQL database. Developers can easily set it up using Docker Compose. Highflame, the company behind ZeroID, also provides a hosted version at auth.highflame.ai. SDKs are available for popular programming languages, including Python, TypeScript, and Rust. Future integrations and features are planned, such as a CLI and a human-in-the-loop approvals API.

Conclusion

As AI continues to evolve, the need for robust identity solutions becomes increasingly important. ZeroID aims to provide transparency and accountability in agentic systems, ensuring that as AI becomes more powerful, it remains accountable. This initiative could significantly impact how identity and credentialing are managed in autonomous systems, paving the way for safer AI interactions.
