It is not hibernating or suspending, just locked. If I lock it and immediately unlock it forces me to use password as it should, otherwise about 40% of the time it just unlocks to my full session as I left it before locking. I lock by physically clicking the lock icon in the top right of the screen. I've not tested by just walking away and waiting. I originally posted here https://askubuntu.com/questions/1012420/ubuntu-17-10-major-security- issue-at-login?noredirect=1#comment1641885_1012420 if that helps. Let me know other info you need to help find a fix. This is a major security issue for me at my location.
