If you can't remember the lock screen password or PIN for your Kindle Fire, you'll need to reset your device. Important: Resetting your Kindle Fire removes all content downloaded to it. Any content you purchased from Amazon is saved to your Kindle Library in the Cloud and remains in the Cloud. You can download that content again if you register your Kindle Fire to your account again. While we're unable to respond directly to your feedback, we'll use this information to improve our online Help. Try saying, "Alexa, call Customer Service".
