Google Nexus 7: How to make your device secure

Yahoo Contributor Network

So you've just received your brand new Google Nexus 7 tablet and after many hours of trying, you've finally unboxed it. Before you start using the device, you should make sure that it is set up securely. After all, this device will be linked to your Google account, and you'll probably be storing important information on it in some form. The last thing you need is a thief being able to steal your identity and commit fraud. Here are a few things you should configure to ensure the security of your data.

Screen Lock

All security settings can be configured from the general device settings menu, in the aptly named "Security" section. The first thing you should do is configure the Screen Lock, which can either be a PIN, Password, Pattern, or Face Unlock. The PIN is a standard 4 digit PIN that should be avoided at all costs, since it is highly insecure. Instead, choose one of the other options and set it up. A password should be complex but obviously not so long that it makes you regret locking your device in the first place. Or, if you use a pattern, make sure to uncheck the "Make pattern visible" option in the settings so that people can't see your pattern as you draw it.

If you are feeling like showing off, set up the Face Unlock feature which will let you unlock your device by pointing the camera at your face. For extra security, enable the "Liveness check" option which requires you to blink before the device will unlock (earlier versions of Face Unlock were easily fooled by a photo of the owner's face). Finally, check the option "Power button instantly locks" so that an unlock method is required immediately after locking the screen.


A new encryption feature might be worth looking into as well, especially if you are using this device for work related activities and will be storing confidential information on it. This feature will encrypt the contents of your device with a password or PIN which is entered when the device starts up. Again, a password is recommended more than a PIN, as long as it is long and complex (contains upper and lowercase letters, numbers, and symbols). Be aware that if you forget this password, you will not be able to access your files or use your device, so only enable it if the security of your data is crucial.

SIM Lock

Finally, an old feature of most devices, but still one that is important: the SIM lock. This feature will add a passcode to the SIM card which is required each time the device starts. Without the correct passcode, the device will still work, but will be unable to connect to a mobile network operator, meaning you won't rack up usage bills that aren't yours if your device is stolen.
