Apple recently emailed Apple ID users with two-step verification enabled to inform them that, upon installing iOS 11 or macOS High Sierra, they will be automatically updated to its newer two-factor authentication method.
Apple introduced two-factor authentication in 2015 as an improved version of its two-step verification method for securing an Apple ID account with both a password and a secondary form of verification. Two-factor authentication requires an Apple device with iOS 9, OS X El Capitan, watchOS 2, any tvOS version, or later.
The two security methods are similar in many ways, but two-factor authentication automatically sends a six-digit verification code to all trusted devices registered to a given Apple ID, whereas two-step verification manually prompts users to send a four-digit code to any SMS-capable trusted device registered.
Two-factor authentication also displays a map on all trusted devices with an approximate location of where an Apple ID sign-in attempt occurred when a user is trying to access the account from an unknown device or on the web.
Apple's two-factor authentication method disables the Recovery Key by default, since offline verification codes can be generated on trusted devices in the Settings app. On iOS, users can still enable the Recovery Key as a backup method in Settings > Apple ID > Password & Security > Recovery Key.

'If you install the iOS 11 or macOS High Sierra public betas this summer and meet the basic requirements, your Apple ID will be automatically updated to use two-factor authentication. This is our most advanced, easy-to-use account security, and it's required to use some of the latest features of iOS, macOS, and iCloud.
Once updated, you'll get the same extra layer of security you enjoy with two-step verification today, but with an even better user experience. Verification codes will be displayed on your trusted devices automatically whenever you sign in, and you will no longer need to keep a printed recovery key to make sure you can reset a forgotten password.'
iOS 11 and macOS High Sierra public betas will be available in late June through the Apple Beta Software Program. The software updates will be available for all eligible iOS devices and Macs in the fall.

There are two approaches to preventing root login without a password on a MacOS High Sierra machine, you can use Directory Utility or the command line.

Using Directory Utility to Lock Down Root
1. Open Spotlight on the Mac by hitting Command+Spacebar (or clicking the Spotlight icon in the upper right corner of the menubar) and type in “Directory Utility” and hit return to launch the app
2. Click the little lock icon in the corner and authenticate with an admin account login
3. Now pull down the “Edit” menu and choose “Change Root Password…”
4. Enter a password for the root user account and confirm, then click “OK”
5. Close out of Directory Utility
If the root user account is not yet enabled, choose “Enable Root User” and then set a password instead.
Essentially all you are doing is assigning a password to the root account, meaning that logging in with root will then require a password as it should. If you do not assign a password to root this way, amazingly, a macOS High Sierra machine accepts a root login without a password at all.
Using the Command Line to Assign a Root Password
Users who would prefer to use the command line in macOS can also set or assign a root password with sudo and the regular old passwd command.
1. Open the Terminal application, found in /Applications/Utilities/
2. Type the following syntax exactly into the terminal, then hit the return key: sudo passwd root
3. Enter your admin password to authenticate and hit return
4. At “New password”, enter a password you won’t forget, hit return, and confirm it
Be sure to set the root password to something you will remember, or perhaps even matching your admin password.
