As you know, many Twitter users use third-party applications, rather than a web interface, to write tweets. So, Carolyn Penner reported on Twitter 's blog that starting yesterday - August 31 - all Twitter applications should use OAuth.
OAuth is an authentication method that allows you to use applications without giving them their password.
With basic authentication, you need to specify a username and password to access Twitter, and the application must store and transmit this information over the Internet each time the application is launched. With OAuth, everything is different. The application does not store your password, you simply claim access to the application. And if the user changes his password, the applications will continue to work. ')
You can cancel access to the application at any time. To see which applications are given permission, just go to the Settings section of the Connections tab .
Fortunately, the developers were aware of the transition to OAuth since December last year, so they managed to update their applications. And many applications, including Echofon, TweetDeck, Twitterrific, Seesmic, Twitter for Android, Twitter for iPhone and Twitter for BlackBerry, already use OAuth. If you are using a third-party application, then check that you have the latest version. Otherwise, it may be that it does not work at all.
