Step 1

Press the center button on your iPhone to engage it. Find the “Settings” buttons. Press the Settings button.

Step 2
Once you have pressed the Settings button, it will take you to a General screen and that screen will have a vertical list, which starts with About, Usage, Network, etc. Scroll down until you see Passcode lock.

Step 3
Press Passcode lock. At the top of this screen you will see something that says “Set Passcode” and the option to enter a four digit passcode beneath. Enter your four digits. Re-enter them.

Step 4
Now you will be taken back to the Passcode lock, where it will say “Turn Passcode Off” at top. This indicates that it is on. Below you can adjust the settings… ideally, the Require Passcode can be adjusted to turn on after 1 minute, 5 minutes, 15 minutes, 1 hour or 4 hours.

Step 5
I set mine for 5 minutes because it is annoying having to constantly engage the passcode and yet, assuming you lose your phone, you want that protection on. The way to do this is by pressing “Require Passcode” and pressing the “Five minutes” button. A check will appear on the right side of five minutes to show that this amount of time has been engaged.

Step 6
Press “Passcode lock” at the upper left hand to get back to your Passcode Lock Screen. Press General to return to your main security screen. Press the center button on your phone to return to your phone’s main screen.
