Compare open source, agent-native identity management with Auth0's developer identity platform. Find the right solution for your AI agent security needs.
by OpenA2A
Purpose-built for AI agents. Cryptographic identity, capability-based access, and continuous trust scoring. Open source and self-hosted.
by Okta
Developer-friendly identity platform for web and mobile apps. SSO, social login, MFA, and user management for human users.
Auth0 excels at authenticating human users in web and mobile applications (OAuth, social login, passwordless). AIM is purpose-built for autonomous AI agents that need cryptographic identity, behavioral trust scoring, and capability-based access control. Different identity subjects require different solutions.
| Feature | AIM | Auth0 |
|---|---|---|
| Primary Focus | AI agent identity | Human user authentication |
| Licensing | Apache-2.0 (Free) | Freemium (paid tiers) |
| Deployment | Self-hosted or Cloud | SaaS (Private Cloud extra) |
| Cryptographic Agent Identity | Ed25519 per agent | Not designed for agents |
| Continuous Trust Scoring | 8-factor real-time | Bot detection (opposite goal) |
| Capability-Based Access | Code-level enforcement | RBAC for humans |
| MCP Server Attestation | Native support | Not supported |
| AI Framework Integration | LangChain, CrewAI, etc. | Not applicable |
| OAuth/OIDC for Humans | Not the focus | Full support |
| Social Login | Not applicable | 30+ providers |
| Developer Integration | One line of code | SDKs + quickstarts |
| Source Code Access | Full access | Closed source |

with Auth0
AIM secures AI agents. Auth0 authenticates human users. Different tools for different jobs.
from aim_sdk import secure
# Register and secure an AI agent
agent = secure(
"data-analyst",
capabilities=[
"database:read",
"api:call"
]
)
# Agent has cryptographic identity
# Capabilities are enforced
# Trust is continuously scored// Authenticate a human user
import { Auth0Client }
from '@auth0/auth0-spa-js';
const auth0 = new Auth0Client({
domain: 'your-domain',
clientId: 'your-client-id'
});
// Human logs in via browser
await auth0.loginWithRedirect();AIM and Auth0 solve different problems and complement each other perfectly:
Human identity + Agent identity = Complete identity coverage for AI-powered applications.
AIM provides what Auth0 can't: purpose-built identity for AI agents. Open source, self-hosted, free forever.
