Identity Management for Agentic AI [pdf] (2025)

📝 Discussion Summary (Click to expand)

Theme 1 – Technical standards and implementations for AI‑agent identity

“I work at Proof, and we're working on x401 as a means for agentic authorization … a website that wants to authorize who you are (say, to book a flight or sign a waiver for go kart rental) … the endpoint returns 401 and defines in a header what info it needs about you (over 18? you're actually John Doe? etc.)” – x401throaway

“We settled on the core primitives of W3C DIDs for identity, Verifiable Credentials for delegations, and StatusList bitstrings for revocations as the ‘minimal set of ingredients’ that address all the above.” – udbhavs

“I wrote a solution for this, and it has been working across several organizations for some months now. I run it as a public service at https://awid.ai … Trust rooted in the DNS. Multiple registries supported. did, verifiable stable identities. Certificate‑based teams.” – juanre

Theme 2 – Clarifying authentication vs. authorization and HTTP status codes

“Uh, not sure I agree with your terminology – one does not authorize who you are. You authenticate yourself, certain tokens authenticate your identity with varying levels of strength … Authorizations are what are granted to an authenticated identity, typically with a specified scope and duration.” – 0xWTF

“Maybe related. I was always confused with the authorization header and 401 status code (unauthorized). I've only ever seen authorization header containing credentials (i.e. authentication, who you are) instead of authorization (what you can do). Also everyone returns 401 when unauthorized (i.e. can't do a thing), instead of 403 (forbidden, i.e. can't do the thing). When 401 should probably be ‘unauthenticated’ (we don't know who you are, so we can't authorize you).” – Knufferlbert

Theme 3 – Need for human accountability and liability for agent actions

“> agent-native identity I think this is the cursed part of the mission. What are we actually arguing for here? Something like a limited liability corporation? ‘Agent-native identity’ reads to me the same way that ‘unaccountable’ does. Creating a ‘MyAiRobot’ account in GitHub and then rejecting ownership over that account is where this starts to turn into a problem. We need to make a human responsible for these things at all times.” – bob1029

🚀 Project Ideas

Agent Identity Verification Service (AIVS)

Summary

  • Provides a cloud‑based API for issuing and verifying W3C Verifiable Credentials tied to DIDs for AI agents, solving the lack of trusted agent identity in MCP‑style interactions.
  • Core value: lets developers prove an agent’s authenticity (e.g., “this agent acts on behalf of user John Doe”) with cryptographic guarantees that integrate with existing OAuth/OIDC flows.

Details

Key Value
Target Audience SaaS platforms, agent builders, and enterprises needing to trust autonomous agents
Core Feature Issue DID‑based VC (e.g., proof of human‑in‑the‑loop, role, or device) and verify them via a simple REST/JWT endpoint
Tech Stack Node.js/TypeScript, @web5/api (DID/ICW), Veramo library, PostgreSQL, Docker, Kubernetes
Difficulty Medium
Monetization Revenue-ready: tiered API calls (free 10k/mo, then $0.001 per verify/issue)

Notes

  • HN commenters highlighted the need for “agent‑native identity” and trusted delegation (udbhavs: “We settled on the core primitives of W3C DIDs for identity, Verifiable Credentials for delegations…”).
  • AIVS gives them a ready‑made, standards‑based backend they can drop into their MCP or custom agent frameworks, sparking discussion on verifiable credential adoption for agents.

Agent Authorization Middleware (AAM)

Summary

  • A lightweight library that sits between an agent and a service API, automatically handling 401 responses by triggering a human‑approval flow (push, email, or in‑app prompt) and injecting the required claims (age, identity, consent) as defined by the x401 spec.
  • Core value: removes the manual boilerplate for “agent‑on‑behalf‑of‑user” approvals while keeping the user in the loop for sensitive actions.

Details

Key Value
Target Audience Developers building AI agents that perform payments, bookings, or other consent‑gated actions
Core Feature Intercept HTTP 401, launch approval UI, cache and replay request with verified credentials
Tech Stack Go (middleware), React Native/Web for approval UI, WebPush API, Redis for session store, OpenAPI spec generator
Difficulty Low
Monetization Hobby

Notes

  • x401throaway described a flow where “the endpoint returns 401 and defines in a header what info it needs about you… we’re putting IAL2 verification in front of this.” AAM implements exactly that pattern, making it easy for HN users to adopt without rolling their own.
  • The middleware can be discussed as a reference implementation for the emerging x401 standard, encouraging community contributions and feedback.

Agent Identity Registry & Discovery (AIRD)

Summary

  • A hosted, DNS‑based DID resolution service that lets agents publish their DID documents and verifiable credentials, enabling other services to discover and trust agent identities without a central IdP.
  • Core value: provides a simple, decentralized “phone‑book” for agents, similar to awid.ai but with a managed UI, SLA, and optional premium features like reputation scoring.

Details

Key Value
Target Audience Platforms, marketplaces, and developer communities that need to verify agent identity across domains
Core Feature Register DID, upload VC, resolve via DNS (did:web) with optional reputation badges and revocation lists
Tech Stack Rust (DNS server), IPFS for VC storage, PostgreSQL for metadata, React dashboard, Terraform for deployment
Difficulty Medium
Monetization Revenue-ready: $9/mo per namespace for basic registry, $49/mo for reputation & analytics add‑on

Notes

  • juanre’s awid.ai shows demand for “Trust rooted in the DNS. Multiple registries supported. did, verifiable stable identities.” AIRD offers a production‑grade, hosted version that HN users could rely on instead of self‑hosting.
  • Provides a concrete platform for discussing decentralized identity standards (DID, VC, StatusList) in the agent context, likely to generate lively threads on interoperability and governance.
