If you've ever written any code to authenticate with Twitter, you may have been confused by all the signature methods and base strings. You'll be happy to know that OAuth 2 has vastly simplified the process, but at what cost?

Join O'Reilly author Aaron Parecki for a webcast presentation that will give an overview of OAuth 2, starting with:

• Various options for building web apps and native apps
• What the end user sees
• What developers using an OAuth 2 API deal with
• What developers of OAuth-2-compliant APIs will need to know to successfully implement an OAuth 2 service of their own
