The beauty of jailbreaking your device is that it allows users to perform hacks on the device, and achieve functionality which are otherwise not possible or allowed. Here is one one such little hack which saves you from those repeated, irritating "password prompts" when you install anything from iTunes Appstore on your Apple iPhone, iPad or iPod Touch.

To get started search and install "PasswordPilot" package from Cydia (BigBoss repo), once installed configure it to store your password and it will automatically fill-in your appstore password as shown in video demonstration below. This comes specially handy in-cases where you have a tough-to-type and remember secure password.
