Websites should be careful when implementing passive noti?¬?cation.
They need to do so in such a way that gives a user the option
to dismiss them permanently.

?– Perspective: Passive User Noti?¬?cation
During user testing of these scenarios, when users used CardSpace, they sometimes
found themselves changing contexts (switching back from the protected
desktop after sending a token) and suddenly not understanding what had just
transpired. Even though they expected to be logged in to the website, they didn??™t
react as if that is what they had done. Adding in a pop-up message to notify
users about what they had done was very effective and well received. After testing
was completed, a user-experience expert pointed out that pop-up messages
work well in testing, but in the real world, users become irritated with them
quickly and will complain.
