From the developer: "Password Popup provides a secure and unbelievably easy way to keep track of User ID and Password information. These days there are passwords for everything, and you might be surprised when you start counting how many you actually keep track of and use. With security more important than ever, using the same simple User ID and Password for everything is not a good idea. Password Popup allows you to maintain unique and complex passwords while only needing to remember one password - the password that brings up the Password Popup interface."
