Twitter just rolled out a pretty nice two-factor authentication system using your smart phone as the second factor: The new two-factor system works like this. A user enrolls using the mobile app, which generates a 2048-bit RSA keypair. The private key lives on the phone itself, and the public key is uploaded to Twitter. When Twitter receives a new login request with a username and password, the server sends a challenge based on a 190-bit, 32 character random nonce, to the mobile app -- along with a notification that gives the user the time, location, and browser information associated with the login request. The user can then opt to approve or deny this login request. If approved, the app replies to a challenge with its private key, relays that information back to the server. The server compares that challenge with a request ID, and if it authenticates, the user is automatically logged in. The link for this article located at Schneier on Security is no longer available. .

Twitter officially disabled Basic authentication this week, the final step in the company's transition to mandatory OAuth authentication. Sadly, Twitter's extremely poor implementation of the OAuth standard offers a textbook example of how to do it wrong. . This article will explore some of the problems with Twitter's OAuth implementation and some potential pitfalls inherent to the standard. I will also show you how I managed to compromise the secret OAuth key in Twitter's very own official client application for Android. OAuth is an emerging authentication standard that is being adopted by a growing number of social networking services. It defines a key exchange mechanism that allows users to grant a third-party application access to their account without having to provide that application with their credentials. It also allows users to selectively revoke an application's access to their account. Some of the more technical aspects of this article will be easier to understand if you have a basic familiarity with the standard and the problems that it is trying to solve. We published a primer earlier this year that you can refer to if you are looking for additional background information. The article located at arsTechnica is no longer available. .
