Lock your screen or device
You wouldn't go out for the day and leave your front door wide open, right? The same principle applies to the devices that you use. You should always lock your screen when you finish using your computer, laptop or phone. For added security, you should also set your device to automatically lock when it goes to sleep. This is especially important for phones or tablets, which are more likely to get misplaced and discovered by people that you don’t want to access your information and home computers that are in shared spaces.
On many computers, you can lock your screen by going into your computer’s Systems Preferences. For your phone or tablet, locking your device with a PIN or pattern helps provide an extra layer of security for your data. On Android devices, you can set your lock by following these simple steps.
