How to setup smart lock in Android Lollipop ?

I. What is smart lock in Android Lollipop?

Sometimes, it is annoying to type PIN or password again and again to unlock the Android device screen.  But you can not afford turning off the security settings for the phone.

Android Lollipop introduced smart lock to solve this problem.

So, Android Lollipop can use your location, your connected devices or your face to unlock the phone automatically.  When you are in pre-assigned trusted location, or your Android device is connected to a trusted Bluetooth (or NFC) device, you can just swipe to unlock the phone without entering PIN or pass-code.

Face unlock actually has been introduced since Android Jelly Bean. It is apparently improved significantly in Android Lollipop.

For trusted devices, Motorola introduced Motorola Skip for Moto X based on NFC tags. But no other vendors provide similar options.

For most Android users, smart lock in Android Lollipop is totally new.
