ZeroID is a groundbreaking open-source identity platform that introduces a robust identity and credentialing layer tailored specifically for autonomous agents and multi-agent systems. This platform is designed to tackle the pressing issue of attribution in agentic workflows.

The core challenge that ZeroID addresses is ensuring clear attribution within complex workflows where an orchestrator agent delegates tasks to sub-agents. In traditional setups, sub-agents may interact with APIs, create files, or execute commands, but existing solutions lack adequate traceability. Current methods, such as shared service accounts, do not provide a delegation trail. Moreover, standard OAuth 2.0 and OpenID Connect (OIDC) protocols were not originally designed for scenarios where agents operate asynchronously, spawn subordinate agents, or cross organizational boundaries without human intervention at every step.

The Attribution Problem

ZeroID utilizes RFC 8693 token exchange to establish verifiable delegation chains. When an orchestrator assigns tasks to a sub-agent, the resulting token retains the sub-agent’s identity, the orchestrator’s identity, and the original authorizing principal. This approach ensures that permissions are automatically reduced at each delegation step, preventing a sub-agent from gaining permissions beyond what the orchestrator already possesses.

Sharath Rajasekar, CEO of Highflame, emphasizes the importance of this innovation, stating, “The identity layer for the agentic era is being written right now. If we don’t get this right, we’re going to end up with systems that are powerful but fundamentally unaccountable. Identity infrastructure needs to be transparent and verifiable.”

Revocation and Real-Time Access Evaluation

In addition to secure delegation, ZeroID incorporates the OpenID Shared Signals Framework (SSF) and the Continuous Access Evaluation Profile (CAEP) to facilitate real-time token revocation. This means that revoking a token at any point in a delegation chain will immediately invalidate all downstream tokens that are derived from it.

For applications where round-trip network requests are costly, ZeroID provides Software Development Kits (SDKs) that support local JSON Web Token (JWT) verification against a cached JSON Web Key Set (JWKS) endpoint. While this method enhances speed, it does not account for real-time revocation status, thereby placing the onus on the implementing service to balance latency and revocation immediacy.

Deployment and SDKs

ZeroID operates as a containerized service powered by PostgreSQL. Developers can quickly set up the database and server locally using a Docker Compose configuration. Additionally, Highflame offers a hosted version of ZeroID at auth.highflame.ai. The platform supports SDKs for popular programming languages, including Python, TypeScript, and Rust.

Currently, ZeroID integrates with projects such as LangGraph, CrewAI, and Strands, with plans for future enhancements. Upcoming features include a Command Line Interface (CLI), Client-Initiated Backchannel Authentication for agents requiring user authorization during tasks, a human-in-the-loop approvals API, and a GitHub Actions OIDC upstream validator.

Developers and organizations interested in implementing this innovative identity management solution can find ZeroID available on GitHub.
