The majority of Tweets are sent or read on applications built by the developer community. Likewise, there is a ever-growing number of third-party applications that bring value to users in a variety of new ways. As we notified developers in April, on June 30th we’re changing the way that all Twitter applications interact with our platform by requiring the use of OAuth for authenticated access. OAuth is a technology that enables applications to access the Twitter platform on your behalf without ever asking you directly for your password. For users, this means increased usability, security, and accountability for the applications that you use every day. Many developers have already switched their applications over to use OAuth, and we’re here to help for those who haven’t. If you are a developer and still need to make this necessary change, you can read more about the OAuth transition and the resources available to you on the Twitter developers website.
