#OAuth

  • Aaron Parecki

    Hi, I'm Aaron Parecki. I write about OAuth here, and I give talks about OAuth 2.0. Below you'll find my recent posts about various OAuth-related things, including talks I'm giving. I've also written two community resources about OAuth:

    OAuth 2.0 Simplified is a guide to OAuth 2.0 focused on writing clients that gives a clear overview of the spec at an introductory level.

    In 2017, I published a longer version of this guide as a book, available on oauth.com as well as a print version. The book guides you through building an OAuth server, and covers many details that are not part of the spec. I published this book in conjunction with Okta.

    The "Agent Verified" signup flow from WorkOS is exactly what I've been telling the agent platforms they should be doing with Cross App Access! Very cool to see this launch! 👏

    https://workos.com/auth-md/docs/flows/verified

    "The agent's provider — OpenAI, Anthropic, Cursor, or any trusted agent platform — attests to the user's identity at registration time. Your service verifies the attestation and issues credentials synchronously, no human interaction required."

    In Cross App Access terms:

    • The "agent platform/provider" is the ID-JAG issuer, because users are already signed in to those platforms when they use agents
    • The "service" is the ID-JAG consumer (the Resource AS), and issues an access token if the ID-JAG is trusted and valid

    You can test this out in the Cross App Access sandbox today! https://xaa.dev/
