Cyber Security is becoming important part of the software industry today. Recently LastPass Software which provides users with the single sign on  functionality was under attack from the hackers recently. Similarly lot of other software technologies are coming up will provide single sign on functionality. Recently I got a chance to work on application called Twigloo which also provides single sign on feature and keeps user info in a protected manner over servers. On visiting their website www.twigloo.com I found that they are able to maintain such security by the use of shared secret mechanism. I would like to see many more applications which provide similar secure feature.
