A reboot of BrowserID — the protocol behind [Mozilla Persona](https://en.wikipedia.org/wiki/Mozilla_Persona), which I worked on at Mozilla — rebuilt in Rust and re-centered on AI agents. Agents get their own cryptographic identity, delegated from a human, scoped by signed warrants to exactly what the human approved, and revocable at any time. Everything verifies offline against DNS-rooted signatures, so no company sits between a site and its users — and human passwordless sign-in comes along for free.
