Replaces API key sharing with OAuth 2.0, but enterprise already has Keycloak, Auth0.

Strengths

•No external database dependency—in-memory storage simplifies self-hosting.
•Client Credentials flow purpose-built for agent auth, not bolt-on user identity.
•Live demo + React admin UI lower friction vs. bare-bones OAuth servers.

Weaknesses

•Hardcoded admin credentials (admin/admin) is a security liability, not a config best practice.
•No persistence layer means tokens vanish on restart—unsuitable for production multi-instance deployments.

Post Description

MachineAuth is a self-hosted OAuth 2.0 server for authenticating AI agents and machines.

What is an AI agent in this context? A software bot (like OpenCLAW, Claude Code, etc.) that makes API calls to access protected resources. Instead of sharing long-lived API keys, your agents can authenticate using OAuth 2.0 Client Credentials and receive short-lived JWT tokens.

Why?

No more sharing API keys Short-lived tokens (configurable) Easy credential rotation Industry-standard security
