TwitPic, the largest photo sharing service on Twitter, posted a tweet to their Twitter account tonight announcing that they had just implemented OAuth as the new login method for their site. If you’re not familiar with the OAuth protocol, how it works, or how it affects you as a user, here is the short version.
OAuth is an open protocol that allows a user to share content stored on one site with another site without having to fork over the login credentials. In other words, you no longer have to provide TwitPic with your username and password to login to their site. Instead, you will need to click the “Sign in with Twitter” button located in the top right corner, when prompted enter your username and password on Twitter.com, and then click the “Allow” button to grant access to TwitPic. This allows TwitPic to connect to your Twitter account so it can access your data, but at no time will TwitPic receive your username and password. To learn more about OAuth visit their Web site here.
