Apple macOS High Sierra: can login as root with empty password!

Dear @AppleSupport, we noticed a *HUGE* security issue at MacOS High Sierra. Anyone can login as "root" with empty password after clicking on login button several times. Are you aware of it @Apple?

You can access it via System Preferences>Users & Groups>Click the lock to make changes. Then use "root" with no password. And try it for several times. Result is unbelievable! pic.twitter.com/m11qrEvECs

Reminder: if you need a complex password (say to set as a root password) you can use the Password Assistant via Sys Prefs -> Users & Groups -> Change Password… click key icon. Copy password, cancel password change. pic.twitter.com/PtXsM9d3W8
