• 

  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.

  In two weeks I'll be speaking at the MCP Dev Summit in San Francisco! It's going to be a great day packed with back to back sessions.
  
  In less than a year, the MCP project has quickly reshaped how developers are building AI agents. My talk, "Intro to OAuth for MCP Servers", will cover the basics of the new MCP authorization protocol and set the stage for building secure MCP servers.

  At long last, the OAuth working group has finished the Best Current Practice for OAuth 2.0 Security and it was just published as RFC9700! This has been a long time in the works, and I'm very thankful to everyone who has helped out with it over the years!
  
  https://www.rfc-editor.org/rfc/rfc9700.html
  
  This is one of the major inputs to OAuth 2.1, so I'm also very excited to be able to move that forward this year as well!
