Ubuntu not asking for password to log in

Question

I am trying to lock my system, but it seems like though it is locking but it is not asking for password to login.

Even when I changed setting from Settings > User Account and rebooted my system the password is by-passed.

I tried everything, but don't know which setting is causing this problem. If anyone can help with this?

Run this command in terminal: gsettings get org.gnome.desktop.lockdown disable-lock-screen . What does it tell you ? — Sergiy Kolodyazhnyy, Feb 03 '16 at 14:59
@SergiyKolodyazhnyy Tells me false. What should I do next? The given answers are not helping me. — Porcupine, Jun 13 '18 at 10:19
@Nikhil If it says false , then this setting is alright, so not the problem. — Sergiy Kolodyazhnyy, Jun 13 '18 at 23:05

I found my answer here. Since these questions have different phrases I thought of not deleting my question. This might help somebody else.

Run sudo grep nopasswd /etc/*

This will display at least 2 lines:

/etc/group:nopasswdlogin:x:112:`<login name>`   
/etc/gshadow:nopasswdlogin:!::`<login name>`

Edit those files with sudo and remove only from those lines and save.

Restart the computer and now it should ask for the password again!

Run the following command from your terminal:

sudo gpasswd -d $USER nopasswdlogin

It should solve your problem.
