If you lose your iPhone, or if a thief I manages to slip it out of your pocket, all of your email and data are in someone eIse's hands. Stop them from peeking by locking your phone with a passcocle. It’s really easy to set up. Tap Settings > General > Passcode Lock, and set a 4-digit passcode by entering it twice. Just be sure to pick a different PIN than the one you use for your bank card. Tap Require Passcode to change the duration of idle time before the iPhone asks for the passcode again, saving yourself from annoyance. As Apple suggests, a shorter time period is more secure. Chances are, you'l| be the one entering the code most frequently, so try to strike a balance between convenience and the need for security. Keep in mind, however, that if someone wants to return your lost phone or contact your family in an emergency, they'lI be stuck at that input screen. To fix this, on your computer, use an image editor to create a picture containing your contact info. Email the graphic to your phone, and set it as wallpaper. Those details will appear behind the passcode prompt.
