How to Password Protect a Book on the Kindle

There are over a million e-books available for the Amazon Kindle, but not all of them are appropriate for all audiences. If you're using the Kindle Fire version of the device, you can use a password to restrict access to your media and ensure that the content is hidden from prying eyes. A Kindle password allows you to lock the entire device, while parental controls let you restrict specific types of media.

Set Kindle Password

Turn on the Kindle and access the home screen. Tap "Quick Settings."

Press "More" and choose "Security." Locate the "Lock Screen Password" item and move the corresponding switch to "On."

Enter a password when prompted. The Kindle asks for this password any time it is turned on or returns from sleep mode.

Enable Parental Controls

Turn on the Kindle. Swipe your finger in a downward motion from the top of the screen. The notification bar appears. Tap "More."

Select "Parental Controls." Tap the password field, and enter a parental control password with a minimum of four characters. Reenter the password in the "Confirm password" field and tap "Finish."

Press the "On" button in the "Parental Controls" section. Tap "On" for the specific parental controls that you want to enable. Turn "Password Protect Purchases" and "Password Protect Video Playback" to restrict access to the Amazon Store and Videos, respectively.

Tap "Block and Unblock Content Types" to set your preferences for different types of media, including books and photos. Press "Block" to restrict an item, or "Unblock" to leave the media available. The Kindle will require your parental password for these items.
