Have your devices go to sleep quicker

Password-protected PCs, Macs, tablets and smartphones all have limit points at which they lock their screens, requiring re-entry of the passcode or PIN. The time frame for relocking is changeable, but the safest option is to force anyone attempting to log in to re-enter the device password immediately. That way, you don’t have to worry about someone picking up your phone or laptop and being able to access its contents.
