Smart Lock allows you to set security bypasses in certain places or when you connect to certain devices, allowing you to skip your screen lock type giving you quicker access to your device.
To be able to use Smart Lock, you will need to set up screen lock type. This can either be a Pattern, PIN or Password.
If you do not have a pattern, pin or password set, you will be prompted to set one up while setting up your Smart Lock.
Smart Lock is a feature of devices running Lollipop and Marshmallow.
