Security - O'Reilly NOOK Manual

Security

You've got two security settings on your NOOK Tablet:
• Device lock passcode. If you're worried that unauthorized people may
get their hands on your NOOK Tablet, tap here and from the screen that
appears, type a four-digit passcode. From now on, whenever your screen
locks, entering this code is the only way to unlock it. So make sure you
remember the passcode.
