How to create multiple user account accounts with passwords on it?
Multi-User was added with Android 4.2 -- you're running 4.0, so there's no native way to go multi-user without upgrading your system.

If you have your device rooted, you might want to take a look at SwitchMe Multiple Accounts, which works with Android 2.1 and up. With Android 4.1, you could make use of the User Management app. Both would enable you to have a multi-user feature on your device.
