below in order of weakest to strongest:

Swipe – no protection, but you have quick access to the Homescreen

Face Unlock – unlocks your device when you look at it

Unlock pattern – draw a simple pattern with your finger to unlock your device

Unlock PIN – enter a numeric PIN of at least four digits to unlock your device
