12. Find my iPhone (or Mac or iPad)
A popular hacking method is known as the “evil maid” attack. These are targeted, physical attacks on your data. To stay secure at business conferences, it’s often recommended to use a “burner” computer that doesn’t contain your company’s secrets.
That being said, not everyone will be a target of physical attacks, but if your device is stolen you will want to be able to lock it down and possibly get it back. Find My iPhone is an iCloud feature that can help you find, lock, or erase your iOS or macOS device remotely. You may also want to consider setting up your iOS device to wipe its data after 10 failed login attempts.
