• 

  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.

  I've given many talks about how mobile apps can't be deployed with a secret, and using Twitter's 2013 "hacks" as an example. I'm just going to leave this completely unrelated string of random characters here for no particular reason

  PSA: If you use Twitter to sign in to stuff, you should double check you have another way to get in to those accounts asap. With Twitter charging ??? for API access next week, you have no way of knowing whether the apps you use are going to pay that.

  It's been a while since I've set up an Amazon Echo device. Do I need to come over there and teach some Amazon folks about the OAuth Device Flow? There is a better way than making me type my password on this screen!
