No ask password when logging in system

[Мария]

I create the new user without password. When I login in the system, I changed password.

But after reboot in the login screen I login without password.

But if I locked screen, I need enter the password for returning in system.

1) Ubuntu 14.04

2) unity-control-center: 14.04.3+14.04.20140922-0ubuntu1

3) What you expected to happen: In the login screen I need enter password, before logging

4) What happened instead: In the login screen I login without password

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Check the "Automatic login" selector in the User Accounts section of the control center, chances are good you're still set to log in automatically.

There are two users in the computer. The problem is with user which was created without password.
