My thanks to WorkOS for sponsoring DF last week to promote Auth.md, their new open protocol for AI agent registration. (Who’d have thunk that I’d be getting paid to promote new uses for Markdown 22 years after releasing it?)
Sign-up forms were built for humans in browsers, so how do AI agents programmatically register with services? That’s the question Auth.md aims to answer. It’s a single Markdown file you host at your domain that tells agents how to register your users, which flows you support, what scopes you expose, and how credentials get issued. It’s like robots.txt but for agent registration.
Cloudflare, Firecrawl, and Resend have already adopted it.
An open protocol authored by WorkOS. Read the spec.
