This issue is caused by the Users and Groups utility which is part of `gnome-system-tools`. When changing the password from "Asked on logon" to "Not asked on logon" the user is added to the `nopasswdlogin` group and this is what causes the switch-user screen to not ask for a password.

If you select the option to not require a password to login during installation, it is not possible to bypass authentication when switching users. This is because `autologin-user` is set to your username in `/etc/lightdm/lightdm.conf` and that works correctly.

`gnome-system-tools` was originally included in Ubuntu MATE because it offers user and time management features. But it can now be removed from the Ubuntu MATE default install because recent versions of MATE Control Center provide user and time management.
