Problem
Microsoft touts security as one of the primary tenets of its operating systems. While claiming that, because the source is open for Linux, it is very insecure. Linux requires that you have a username and a password to be able to login and use the system. While Microsoft does require a username to sign onto the system, it does not require a password for the user.
Since a password is not required to use a Windows system, how does that impact security? What happens when a user does not have a password on a Linux system? Are there any accounts on a Linux system that do not have passwords? If so, why do they not have passwords?
