With iOS 10 came the removal of Slide to Unlock, which now if the slide right gesture is repeated sends you to the Today view Widgets screen complete with weather, calendar events, tabloids and news, Siri app suggestions, stocks, maps, and whatever optional widgets you have enabled on the iPhone or iPad. This Widget screen is accessible from the lock screen by default on any iOS 10 device.
If you don’t want widgets available on the lock screen - you’d prefer to maintain more privacy and not reveal anything about the device itself let alone the calendar or app suggestions, or notifications. For any reason, you can disable and hide the widget section of the lock screen completely
This works to disable the Today view, widgets, and Notification view with any iPhone or iPad running iOS 10 or newer:
1. Open the “Settings” app on iPhone or iPad and then go to ‘Touch ID & Passcode’
2. Under the “Allow Access When Locked” section, toggle the switches next to “Today View” and “Notifications View” to the OFF position
3 . Exit out of Settings and lock the device again, swiping over will now do nothing
Note that you will still have access to widgets, Today view, and notifications from an unlocked iPhone or iPad, just not from the lock screen.
