In iOS 8, you can enable access to a few more features on a locked phone if you choose to. Specifically, you can toggle on the Today and Notifications View screens for Notification Center.
With every iOS release, Apple's privacy settings expand and diversify, and iOS 8 is no exception. The biggest addition to the company's Privacy settings screen comes inside the Location Services submenu; here, you've got a new subsection on sharing your location, more refined control for apps, and new system services toggles.
LOCATION SERVICES: The Share My Location screen lets you turn location sharing on or off globally, lists any friends you're sharing your location with permanently (temporary location-sharing friends won't appear here), and offers a Stop Sharing My Location button for each at the bottom of their contact card.
Apps, too, have slightly more granular settings within Location Services. In iOS 7, you could toggle location services on or off for a specific program; with iOS 8, each app has the "Allow Location Access" submenu, with options for Never, Always, or While Using the App.
Within System Services, you'll find new on/off toggles for the Find My iPhone service, Location-Based Alerts, Motion Calibration, Share My Location, Spotlight Suggestions, and Improve Maps (relocated from the Frequent Locations submenu).
OTHER PRIVACY FEATURES: In iOS 8, you can choose whether to allow third-party apps access to your Camera, Health, HomeKit, and Motion Activity data; those apps you've let in will appear in new Privacy menus named after each of those features.
The Diagnostics & Usage submenu (found at the bottom of the Privacy screen) also has a new toggle: Share with App Developers. If you turn it on, this feature lets third-party developers see anonymized crash data and statistics about how you use their apps.
There are lots of new tweaks and feature additions in the iCloud preferences screen, though most dramatic comes in the form of the new Account submenu.
For one, you can now see which Apple ID your device is logged in to from the Settings screen, as it's now listed below the iCloud submenu. Tap on iCloud, and the top of the settings screen lists your account, a toggle for setting up Family Sharing, your Storage information, iCloud services, and advanced services.
The Account screen is protected by your iCloud password, but once you enter it, you can see and change your email addresses, primary mailing address, and whether you want to receive offers from Apple. There are also fields for viewing or changing your account's birthday, password, security questions, and rescue email address, along with turning on two-step verification. You'll additionally be able to view your primary payment method associated with your Apple ID, though you can't change it from this screen.
