I created Autosign earlier, which combined AgentMail and BrowserUse to let agents pass email verification. It worked for a while but I still faced problems like hCaptcha and other blockers. That made it clear to me that AI agents need an efficient way to sign in that is not a turnaround or bypass solution built on top of human login systems.
Auth-Agent is the result of that. It is the world’s first OpenID Connect provider for AI agents. It provides a standard OAuth 2.1 / OIDC flow but the client is an AI agent instead of a human user. It is open source: https://github.com/auth-agent/auth-agent.
