Using a single Amazon account to manage multiple Kindle devices is a common practice. It allows users to centralize their eBook purchases, subscriptions, and reading progress across all their devices. For instance, a family might share a single Amazon account, enabling each member to access purchased books on their individual Kindles.
The primary benefit of this approach is streamlined content management and cost savings. Instead of purchasing the same eBook multiple times for different users, a single purchase grants access across all registered Kindles. Furthermore, features like Whispersync allow reading progress, bookmarks, and annotations to be synchronized, providing a seamless reading experience regardless of the device used. This method became prevalent with the increasing popularity of eBooks and the desire for convenient digital libraries.
