You should set an automatic screensaver and or sleep timeout.The password protection for sleep and the screen saver can be found under the Security panel.Screen saver settings can be adjusted under the Desktop & Screen Saver panel.Both of these options can be configured from System Preferences, albeit from different sections: While most Macs are set by default to sleep after a period of inactivity, the screen saver functionality often needs to be manually enabled if you'd like to use that as well. To minimize the risk of unauthorized access while you are away from your Mac, you can require a password to wake it from sleep or a screensaver.Then update the Automatic Login field under Login Options. You should consider disabling automatic login by heading to System Preferences and selecting Users & Groups (called "Accounts" in earlier versions of Mac OS X).While automatic login is convenient, it can also allow an attacker with physical access to your computer to access all of your files.To enable it, go to System Preferences, and select the Security panel.
