Show HN: AgentAuth – open-source identity management for AI agents

Hi HN, I built this because I kept running into the same problem: AI agents need to log into websites, and everyone (including me) just hardcodes cookies. It's insecure and breaks constantly.

AgentAuth is a Python SDK that:

- Stores sessions in an encrypted vault (not in your code) - Gives each agent a cryptographic identity (Ed25519 keys) - Scopes access (agent X can only access linkedin.com) - Logs all access for auditing

I also built a Chrome extension that exports cookies with one click.

The goal is to become the identity layer for AI agents — like how OAuth standardized user auth, but for agents.

Would love feedback, especially from anyone building agents or dealing with browser automation.
