When I installed Ubuntu 15, I set automatic logon to "yes". But now I don't want this automatic logon. I want GNOME to ask for password before entering my account. I already tried to set automatic logon off in User Settings but that does not work for me. A possible solution may be deleting my account and creating a new one, but I don't want to do that.

If the GUI doesn't work, use a terminal ;)
Change the configuration file /etc/gdm/custom.conf
:
sudo sed -i 's/^.*AutomaticLogin/# AutomaticLogin/' /etc/gdm/custom.conf
