Why do the other users know the password for your system? Are the supposed to know it?

If you do not want any users other than root to be able to login, create a /etc/nologin file. If this file exists, then only root can login and the contents of the file will be displayed after root successfully authenticates . However, you should never ever login as root using telnet.
