EM Client on shared computer

Can EM Client be configured to require login credentials when it starts?  And not show emails until logged in?  I just set up a user on a shared computer.  I removed the password in the Account settings.  So when it starts it displays the login screen, shows the login name, and prompts for password.  But all the emails show up behind it.  And if I hit cancel, all the emails are accessible.  Thanks, Brooks
