You can easily access a few commonly used features (such as widgets, media playback controls, and Control Center) from the Lock Screen. (For security, USB connections aren’t allowed when iPad is locked.) You can control access to these items when iPad is locked.
If you turn off Lock Screen access to a feature, you prevent someone who has your iPad from viewing any personal information that it might contain (such as an upcoming event in the Calendar widget). However, you also lose quick access to the information yourself.
