Environment.UserName gives you the username of the current user. A password is not needed since the user have logged into windows.

Alternative: WindowsIdentity.GetCurrent()

You can achieve this using Interop Services. Use the below Code.

    [System.Runtime.InteropServices.DllImport("advapi32.dll")]
    public static extern bool LogonUser(string userName, string domainName, string password, int LogonType, int LogonProvider, ref IntPtr phToken);

    public bool IsValidateCredentials(string userName, string password, string domain)
    {
        IntPtr tokenHandler = IntPtr.Zero;
        bool isValid = LogonUser(userName, domain, password, 3, 0, ref tokenHandler);
        return isValid;
    }
