Step by Step Tutorial for Setting a 4 Digit Passcode on iPhone with iOS 17

Before we get started, let’s quickly go over what these steps will do. By following them, you’ll be able to change your iPhone’s passcode from the standard six digits to a simpler four-digit one.

Step 1: Open the Settings App

First things first, you need to open the Settings app on your iPhone.

The Settings app is where you can tweak and customize all sorts of features on your iPhone. It’s typically found on your home screen and has a gear icon.

Step 2: Tap on ‘Face ID & Passcode’

Once the Settings app is open, scroll down and tap on ‘Face ID & Passcode’.

This section controls all the security features for unlocking your iPhone, including passcode settings.

Step 3: Enter Your Current Passcode

After tapping ‘Face ID & Passcode’, you’ll be prompted to enter your current passcode.

Make sure you remember your current passcode because you’ll need it to make any changes.

Step 4: Tap on ‘Change Passcode’

Scroll down and tap on ‘Change Passcode’.

This is where you can update your passcode to something new. If you’ve forgotten your current passcode, you’ll need to reset your iPhone, which is a different process.

Step 5: Enter Your New 4 Digit Passcode

When prompted, enter the new four-digit passcode you want to use.

Choose a passcode that’s easy for you to remember but hard for others to guess.

Step 6: Confirm Your New Passcode

Enter your new passcode again to confirm it.

Double-check that you’ve entered the same passcode correctly both times to avoid any locking issues.

After completing these steps, your iPhone will now be secured with a new four-digit passcode. It’s a simpler and faster way to unlock your iPhone, but still keeps your personal information safe.
