Lock Screen not activating?

[magick]

Hi,

I've done a clean install of windows 10 on my laptop. I have the screen set to go off after 5 minutes which it does however when I move my mouse to re-activate it' just goes straight to my desktop and not the lock screen which isn't good for security. How do I set it so that when my screen goes off based on the timings I select in Power & Sleep I have to enter my pin again to get back on the desktop?

Thanks.
