Roboform is simple to install. It automatically places a toolbar into Firefox and Internet Explorer and any time a form appears on a page, Roboform will either complete it with one-click or allow you to save your responses for the future. It can generate (and remember) secure passwords for any site. And encrypt them for complete security.
And, if you work on several computers, you can synchronize across them.
