All, I like to track my AdSense clicks and income without having to be logged into Google all the time. Over the last 3 years, I have been trying a few different widgets and gadgets ... some require the Google Sidebar, other Yahoo Widgets, others again rely on Firefox running. But in the end, I wanted something simple and independent. So I now use SysSense. It is free and seems to do the job simply and efficiently, without requiring me to have any other apps running! It even plays a sound when the earnings are up Sometimes the notifications are a bit erratic, but it does the job quietly and reliably.

I would never use something that asks me for my adsense password. Id rather just take 2 minutes to login to the adsense website rather than risking having my account stolen.
