Show HN: MachineAuth:open source Google login for your AI Agent

As AI agents become autonomous, they need secure, programmatic authentication - just like developers use API keys, but built specifically for machines. The Problem

Your AI agent needs to access protected APIs, but:

     Username/password doesn't work for machines
     API keys are hard to rotate and audit
     Existing OAuth flows are designed for humans, not agents
     No way to verify which agent is making requests

The Solution

MachineAuth implements the OAuth 2.0 Client Credentials flow - the industry standard for machine-to-machine (M2M) authentication.
