Apple Inc.'s (APL) WWDC keynote may be over, but there's still a lot to unpack.

When Apple CEO Tim Cook Cook walked off the stage at McEnery Convention Center in San Jose, Calif. on Monday, June 4, the developer builds for iOS 12, as well as for new macOS 10.14, called Mojave, became available to download. It's in these builds that new features not shown in the keynote were found.

Here are some of the most interesting unannounced features for Mojave and iOS 12.

 1. Face ID for iPads

When iOS 12 becomes widely available in the fall, iPad owners will see some big changes. One of them is the option to secure the tablet via FaceID. Considering the technology required for FaceID, it's unclear whether this option would only be available for only certain iPads.

2. Two faces for FaceID

Instead of recognizing just one face, iOS 12 will now be able to store two faces. This can be a big help for parents who hand off the iPhone or iPad to their children.

3. USB lockout

A new security feature in iOS 12 will prevent USB devices from connecting to the phone while the screen is locked. When selected, this feature will go into effect one hour after locking the phone. This will prevent devices connecting to the phone to unlock it or wipe the data through a USB cable.

4. Mac system update no longer in App Store

In order to update to the newest macOS in the past, users would have to download the new version from the App Store. Mojave will move the update from the Store to System Preferences making it less of a hassle to update. There is also an option to auto-update to the new version.

5. iOS dark mode

iPhone owners will get their own dark mode just like on Mojave. The announcement of this feature will likely come when the next iPhone is announced.

6. iBooks syncs across devices

Like the Stocks app, iBooks will receive an update. Now known simply as Books, the app will sync across different devices so users can pick up reading the same page on their iPad while on their iPhone.

7. Inclusion of password apps

iOS 12 will allow for easier access to password apps such as 1Password with the new Password Manager. The feature will also suggest passwords for other apps.

8. App Store changes

Apple is putting its foot down when it comes to developer sneaking in changes into their apps. Now every change to an app has to be stated in the description of the update.

9. New podcast app functions

Apple Podcast listeners will soon be able to change how they navigate a podcast. In the settings for the app, users can switch from having their headset's navigations buttons go to the next episode of a podcast to letting the button skip forward a certain amount of seconds.

10. Easy two-step authentication

Previously, users with two-step authentication on an app would have to quit the app in order to acquire the password sent over text. In iOS 12, passwords sent by text will be recognized and will autofill in the password section of the app when needed.
