Once you install PassIT.Net it will place an Icon on your desktop.
Now before you run the program, think of a complicated VIP. A VIP is a Very Important Password. This VIP should be strong, reasonably long and it should be something that you can type in rapidly. You can change your VIP at any time so don't worry.
Now click the PassIT.Net icon. The program will request your VIP and then let you into the core of the vault. Now if you quit without making any new accounts, then the system will assume that you do not want to keep your VIP, and you will have to enter it again the next time you start PassIT.Net. So it is best to enter a new account. Just enter a garbage account first by entering a letter in each account field and then save it.
Now you are ready to play with your new PassIT.Net vault. It will become one of your best friends.
