Your phone, laptop, tablet, and other devices are the entry points for most of the data you create and share. Understanding how these devices work—and what can go wrong with them—helps you make better choices about what you use and how you protect it. This category covers the physical devices themselves: what security features they have, how to spot when something's off, and what happens when you connect them to networks or services.
The articles here answer questions like: How do I know if my device has been compromised? What does it mean when my phone or computer is asking for updates, and should I do them right away? How do I safely get rid of an old device without leaving my data behind? What's the difference between the security built into different devices, and does it actually matter for how I use them?
