Amazon offers a way to password protect your Kindle even though the device isn’t one that is likely to carry any of your sensitive info. However, the feature should no doubt appeal to those who are obsessed with privacy or share their device with others and would rather not share with them their reading list.
So, here is how you can set a password on your Kindle.
Tap on the vertical three dots at the top right corner on the Home Screen.
From the menu that appears, tap on Settings.
Next, select Device Options.
Tap on Device Passcode from the list of options that appears.
