Google Nexus 10 (tablet) - Increase security with a custom unlock pattern

Instead of the simple swipe gesture to unlock your tablet, you can set a custom one which can be extremely difficult for a thief to guess.

From your homescreen, go to Menu – Settings – Location and security – Change screen lock. Then chose Pattern to set one up.

It is also a good idea to untick Use visible pattern. Then if someone is watching over your shoulder while you entering your pattern, it will be harder for them to remember the pattern.

If you have forgotten your unlock pattern, then after 5 unsuccessful tries a button will appear saying ‘Forgot pattern’. Press this and you will be asked to enter your Gmail username/password. The tablet will then ask for a new unlock pattern. If you don’t have a Gmail account, then you will have to either call your carrier or factory reset your tablet.
