Whenever you step away from your computer be sure to lock it with a passphrase, even if you are only going to be away for a few minutes. When leaving your computer for an extended period of time, make sure to shut it down.

Password Protecting a Macintosh Computer
To keep the information on your Mac secure when you are away from it, set it to require authentication when it wakes from sleep. When you return to your Mac, type your login name and password to continue working.
To set up a Macintosh with a password-protected screen saver and sleep mode:
- Choose Apple menu > System Preferences, click Security & Privacy, and then click General.
- Select “Require password for sleep and screen saver.”
You can adjust the amount of delay before a password is required in the pop-up menu.
- To lock your screen quickly with fast user switching enabled, choose Login Window from the menu with your user name. Your apps and documents remain open and undisturbed, but your computer is locked.
- Locking the screen doesn’t prevent other users from turning off the computer, restarting it, and logging in to their own accounts. If you think this could happen, be sure to save your work before you leave your computer.
- You can use your administrator name and password to unlock the screen for yourself or a standard user, but not for another administrator.
To put a Macintosh to sleep or activate the screen saver:
- Choose Sleep from the Apple menu ()
- Press the Command (⌘) Option and Media Eject key (⏏) simultaneously.
- If you’re using a Mac notebook computer, close its built-in display.
- Tap the power button on your computer.
To wake up a Macintosh from sleep or screen saver mode
1. Move the mouse or strike any key on the keyboard and wait for the password prompt.
2. Enter your password.
