To do this make sure to select the icon in the upper right, choose name, icon (choose to make desktop shortcut or not) sign-in with username and password, and then you are good to go. Repeat the steps for the other accounts in your household.
If you choose the desktop shortcut option this is a great way for you to stay just in the account you need to be.
Please though be cautious of staying signed in as anyone who opens the computer can then log-in as you. Just please be aware of that. If you are even a little cautious - don't add your account.
