Changing your iPhone passcode regularly helps protect your personal data, photos, apps, and financial information. Whether you want a stronger code or simply need to update it, the process is quick and easy.

This guide walks you through how to change your passcode on iPhone 14, 15, 16, and 17, including what to do if you forgot your current passcode.


Before You Begin

Make sure:

  • ✅ Your iPhone is unlocked
  • ✅ You know your current passcode
  • ✅ Your device is running the latest version of iOS (recommended)

Note: The steps are nearly identical across iPhone 14, 15, 16, and 17 models.


How to Change Your iPhone Passcode

Step 1: Open Settings

  • Tap the Settings app on your Home Screen.

Step 2: Tap “Face ID & Passcode”

  • Scroll down and select Face ID & Passcode.
  • Enter your current passcode when prompted.

If you use Touch ID (older models), the option will say Touch ID & Passcode.


Step 3: Tap “Change Passcode”

  • Scroll down.
  • Tap Change Passcode.

You’ll be asked to enter your current passcode again for security.


Step 4: Enter a New Passcode

After confirming your old passcode:

  1. Enter your new passcode.
  2. Re-enter it to confirm.

How to Choose a Stronger Passcode

By default, iPhones use a 6-digit numeric code, but you can choose stronger options.

When entering your new passcode:

  1. Tap Passcode Options
  2. Choose one of the following:
OptionSecurity LevelDescription
Custom Alphanumeric Code⭐⭐⭐⭐⭐Letters + numbers (most secure)
Custom Numeric Code⭐⭐⭐⭐Longer number-only code
6-Digit Numeric Code⭐⭐⭐Default option
4-Digit Numeric Code⭐⭐Less secure

For better security, choose Custom Alphanumeric Code.


How to Turn Off Passcode (Not Recommended)

If you want to disable your passcode:

  1. Go to Settings
  2. Tap Face ID & Passcode
  3. Enter your current passcode
  4. Tap Turn Passcode Off

⚠️ Turning off your passcode will:

  • Disable Apple Pay
  • Disable Face ID
  • Reduce device security
  • Remove saved passwords from secure access

It’s strongly recommended to keep a passcode enabled.


What If You Forgot Your Current Passcode?

If you don’t remember your passcode, you cannot change it directly. You must erase your iPhone.

Option 1: Use iPhone Reset (If Available)

If you see “iPhone Unavailable”:

  1. Tap Forgot Passcode?
  2. Select Erase iPhone
  3. Sign in with your Apple ID
  4. Restore from backup afterward

Option 2: Use Finder or iTunes (Recovery Mode)

  1. Turn off your iPhone
  2. Connect it to a computer
  3. Put it into Recovery Mode
  4. Choose Restore
  5. Set up the device again

After restoring, you can create a new passcode.

Important: This will erase your device. Make sure you have a backup.


Why You Should Change Your Passcode Regularly

Changing your passcode helps if:

  • Someone learned your code
  • You used your passcode in public
  • You suspect unauthorized access
  • Your phone was temporarily lost
  • You shared your device

Security experts recommend updating your passcode every few months.


Tips for Better iPhone Security

✅ Use Face ID alongside a strong passcode
✅ Enable Find My iPhone
✅ Turn on two-factor authentication
✅ Avoid obvious codes (123456, 000000, birthdays)
✅ Don’t share your passcode
