Sorry, the chinese character has some problem on showing on my computer, I can see only part of them.
I can not make it clear by words, but can you find the password function in the steps of the installing function? This password can be defined by yourself, which would be save in the destination computer and required each time you login.
Further more, you can write a function in the code design page, which uses a special language(someway like VB) used by InstallShield only. The code contains all the steps that you have made. Add one step(function) as you want in the functions. Prompt a dialog to ask the user for a password and save in the table.
