Passport
Cryptographic Identity for Humans, Organizations, and AI Agents
What is a Passport?
A Passport is a cryptographic identity for any entity in the HUMΛN ecosystem — whether that's a human, an organization, or an AI agent.
Think of it as a portable, verifiable ID that follows you everywhere. Unlike traditional identity systems that lock you into a single platform, a Passport is:
Key Components
Passport ID
A unique identifier for the Passport. Format: passport_abc123
passportId: "passport_alice_2024_xyz"DID (Decentralized Identifier)
A globally unique, cryptographically verifiable identifier. Follows the W3C DID standard.
did: "did:human:alice:2024:xyz"Public/Private Key Pair
Every Passport has a cryptographic key pair. The public key is shared; the private key is kept secret.
publicKey: "0x1234...abcd"// Private key is stored securely and never exposedMetadata
Optional information about the Passport holder (email, organization, role, etc.).
metadata: { email: "alice@example.com", organization: "Acme Corp", role: "CFO", department: "Finance"}Types of Passports
Individual
A Passport for a human. Can delegate to agents, verify capabilities, and approve workflows.
type: "individual"name: "Alice Smith"Organization
A Passport for a company or team. Can own resources, delegate to members, and enforce policies.
type: "organization"name: "Acme Corp"Agent
A Passport for an AI agent. Declares capabilities, receives delegations, and tracks provenance.
type: "agent"name: "Invoice Processor"capabilities: ["invoice_processing"]Create a Passport
Common Use Cases
User Onboarding
New users create their Passport as part of sign-up — it becomes their permanent identity across all apps
Agent Authorization
Create an agent Passport, then delegate specific capabilities to it from a human Passport
Multi-Device Sync
Create Passport on primary device, sync to other devices via cryptographic attestation
Team Management
Organizations create member Passports and delegate access based on roles
Audit & Compliance
Every action is tied to a Passport, creating a full audit trail
