When you fill in a web form, the browser may save the information you typed down. Sometimes it looks really helpful, if you plan to go at that page again in future. But when there is somebody else working at the same place, this feature might not seem attractive anymore. For security reasons it is better if the browser could "forget" all logins since otherwise they can be stolen. With the new Handy Password feature logins you type down will not be memorized by a browser. Only Handy Password will remember your auto-filling-in data and protect it with its powerful encrypting tools.
