Passcode icon is a tweak released during this night in Cydia, and with its help we can block access to individual applications of our iDevices. The tweak gives us the opportunity to set a passcode that must be entered every time a certain application is opened, this option being available for any application installed in iDevices. Unlike other similar tweaks, Icon Passcode requires you to enter the same security code when you open the task switcher or the iOS settings menu, so you have total protection for applications.
This is an free tweak Icon Passcode lets you lock any application you like, so for example you toggle photos application to on, when you tap on an icon you have to enter your passcode to launch the app. I know what you're thinking! this is just like the other ones available on cydia. NO! I'll tell you why, Icon Passcode also gives you the option to lock the multitask bar, so you will only have to enter the correct passcode to make the app switcher appear. I have been working on this today to make it the perfect password protection via tapping on icons. making this all look like its apart of the IOS. this is how i think apple should integrate such an awesome idea. Now not only do you have protection on your apps, and switcher, I've made protection the settings itself you when you go into Icon Passcode's settings you have to enter your passcode before you can even see the settings.
Icon Passcode has a settings menu in the iOS Settings application, there you can change that security code and choose which applications are protected or not. The tweak is available for free in Cydia's ModMyi repo.
