Your phone might have years of text messages and emails with personal information, saved voicemails, pictures of your family, GPS location data, browsing history, notes and more. It's a record of your entire life wrapped in a bit of metal, plastic, and glass. Imagine how terrible it would be for someone to get their hands on that information.
That's why you have to set a passcode to keep out casual snoops and install a tracking app to recover or wipe the phone if it falls into the wrong hands. Learn how to do that and other ways to secure your smartphone or tablet against snoops. But what if the thief is a bit more dedicated? Could they spy on your phone without you knowing?
