Setting a screen lock
There are several ways to lock the screen on your device. For example, you can use
the Face Unlock feature, which uses a picture of your face to unlock the screen. You
can also set a screen unlock pattern, a number-based PIN lock, or a text-based
password.
It is very important that you remember your screen unlock pattern, PIN or password.
If you forget this information, it may not be possible to restore important data such as
contacts and messages. Refer to Sony customer support for more information.

For best results, capture your face in an indoor area that is well lit but not too bright, and hold
the device at eye level.
