How to create new user account without password

Question

I would like to programmatically add new local user to a computer. I found the code here. But I would like that the user could login without password. I saw that there is an option UserPrincipal.PasswordNotRequired=true but if I don't use SetPassword() it throws me an exception:

The password does not meet the password policy requirements...

Is it possible to make a new user with no password?

EDIT: the current code, which adds a new user successfully, but I have to provide some password.It is a complete copy from the link provided:

PrincipalContext oPrincipalContext = GetPrincipalContext();

UserPrincipal oUserPrincipal = new UserPrincipal(oPrincipalContext);
oUserPrincipal.Name = sUserName;
oUserPrincipal.SetPassword(sPassword);
oUserPrincipal.DisplayName = windowsUsername.Text;
oUserPrincipal.PasswordNeverExpires = true;
oUserPrincipal.PasswordNotRequired = true;
oUserPrincipal.Save();

GroupPrincipal usersGroup = GroupPrincipal.FindByIdentity(oPrincipalContext, "Users");
usersGroup.Members.Add(oUserPrincipal);
usersGroup.Save();

There are two potential reasons why your code isnt working.

1. Youre not running as admin
2. Your machine is on a domain with a group policy preventing what you want to do.

The code below has been tested on my machine and is working.

void Main()
{
    PrincipalContext oPrincipalContext = GetPrincipalContext();

    UserPrincipal oUserPrincipal = new UserPrincipal(oPrincipalContext);
    oUserPrincipal.Name = "TestUser";
    oUserPrincipal.SetPassword("");
    oUserPrincipal.DisplayName = "TestUser";
    oUserPrincipal.PasswordNeverExpires = true;
    oUserPrincipal.PasswordNotRequired = true;
    oUserPrincipal.Save();

    GroupPrincipal usersGroup = GroupPrincipal.FindByIdentity(oPrincipalContext, "Users");
    usersGroup.Members.Add(oUserPrincipal);
    usersGroup.Save();
}

PrincipalContext GetPrincipalContext()
{
    var dc = new PrincipalContext(ContextType.Machine);
    return dc;
}

Things for you to try, 1. Try it on a machine that is not on your domain. 2. Try it on a machine that does not have any group policies applied. 3. Run your app as admin on the machine that you're having the issue with
