This Plugin provides an option for users to login with Twitter account. As soon as you enable Twitter login option from Control Panel (Control Panel → Instance Settings → Authentication → Twitter), it will show Twitter button on Liferay login page. Upon clicking on that button user will be directed to Twitter login page and asked to signin (also ask for approval to access basic profile details) and then redirect back to after login landing page of Liferay.

Also it will fetch Twitter profile data and create a Liferay user using Twitter's email address.
