How to Protect Your Kindle
Help protect your Kindle in case of loss or theft by adding your contact information and a password on the Kindle Settings page. Protecting your Kindle in these ways means you could get the book reader back — if you’re lucky!
Add your name and phone number to the Personal Info section of the Settings page by pressing the Menu button and selecting Settings. Press the Next Page button until you see the Personal Info option. Select Personal Info and use the keyboard to enter your name and phone number.
To set a password, press the Menu button and select Settings. Press the Next Page button until you see the Device Password option. Select Device Password, and use the keyboard to type a password in the Password and Confirm text boxes. You can then type a hint in the Hint text box to remind you what your password is if you forget it. The password comes up when you wake your Kindle out of Sleep mode. You aren’t required to enter a password to open every e-book you want to read.
To remove password protection, press the Menu button and select Settings→Turn Off next to Device Password.
