3 Smart Ways to Protect Your Smartphone Data

This is a double bummer: Replacing a phone can be expensive, and the personal information we keep on these gadgets is often priceless. Here, tips for keeping your device (and data) safe—and what to do when a thief strikes.

Lock it down. Protect your info by setting a security pin. Only 36% of people do, found a Consumer Reports survey. Avoid serial or repeated numbers (e.g., 1234 or 1111) and pins based on a recent year, says Gary Davis, of security firm McAfee.

Back it up. Use a free cloud service such as Dropbox or iCloud to make copies of your most important data. Get (and remember to turn on!) an app that can locate, lock, and wipe your phone remotely, says CNET.com’s Bridget Carey. Find My iPhone and Android Device Manager are two good options.

Wipe it clean. If your phone is stolen, fire up your anti-theft app right away. Next, call the police, then your carrier. If you don’t recover the device within 30 minutes, erase your data remotely, says Robert Siciliano, personal security consultant. “If you get the phone back, simply restore it.”
