Screen locks offer your devices an important extra layer of security. Each time you want to unlock your device or switch it on, you’ll be asked to enter a PIN, password or fingerprint. This means that if someone gets hold of your device they can’t access the data on your device without entering your password, pattern, PIN or fingerprint.

BEWARE: Don’t use ‘1,2,3,4’ or an ‘L’ shaped pattern!  Are easy for other people to guess.
