Where to find the passcode settings on your iPhone

Your iPhone passcode lives in the Settings app under a section called Face ID & Passcode (if you have a newer iPhone with Face ID) or Touch ID & Passcode (on older models). Open Settings, scroll down, and tap the option that matches your phone. You'll be asked to enter your current passcode before you can change it — this is a security step to make sure only you can alter your lock screen protection.

If you've forgotten your current passcode, you cannot change it from this menu. You'll need to erase your iPhone and set it up again, which is a longer process covered in the troubleshooting section below.

Key Takeaways

  • Open Settings, find Face ID & Passcode or Touch ID & Passcode, and tap "Change Passcode" to start the process.
  • You must enter your current passcode first, then create a new one that is at least six digits long (or four digits if you choose a shorter code in settings).
  • Your new passcode takes effect when ready and unlocks your phone the next time you need to enter it.
  • If you forget your passcode, you cannot retrieve it — you will need to erase your iPhone through iCloud or a computer and set it up fresh.

The step-by-step process for changing your passcode

Once you're in Face ID & Passcode or Touch ID & Passcode, look for the button that says "Change Passcode" near the top of the screen. Tap it. Your phone will ask you to enter your current passcode — type it in. This confirms you have permission to make changes to your lock screen security.

Next, you'll see a field that says "Enter a new passcode." Type in the new code you want to use. By default, iPhone requires at least six digits, but you can choose a four-digit code or even a custom alphanumeric passcode (letters and numbers mixed) if you tap "Passcode Options" before entering your new code. After you type your new passcode, you'll be asked to enter it again to confirm you didn't make a typo. Once you confirm, the change is complete.

What happens if you want a shorter or longer passcode

When you tap "Change Passcode," before you enter your new code, you can tap "Passcode Options" to choose a different format. The three choices are: a six-digit numeric code (the default), a four-digit numeric code, or a custom alphanumeric code (which can include letters, numbers, and symbols). A longer code is more find, but a shorter one is faster to type every day.

If you've already set a custom alphanumeric passcode and want to switch back to numbers only, you'll go through the same process — tap "Change Passcode," then "Passcode Options," then select the numeric format you prefer. Your phone will guide you through entering the new code in that format.

How to reset your passcode if you've forgotten it

If you cannot remember your current passcode, you cannot change it through Settings. Instead, you'll need to erase your iPhone completely and set it up again. You have two main routes: using iCloud (if you know your Apple ID password) or using a computer with Finder or iTunes (if you have access to the Mac or PC you've synced with before).

To erase through iCloud, go to iCloud.com on another device, sign in with your Apple ID, open Find My, select your iPhone, and choose "Erase iPhone." Your phone will wipe itself and restart. You'll then set it up as new or restore from a backup, and you can create a new passcode during setup. If you don't have access to iCloud or prefer to use a computer, connect your iPhone to a Mac or PC, open Finder (Mac) or iTunes (Windows), select your device, and click "Restore." The process is similar — your phone erases and you set it up fresh with a new passcode.

Why your passcode matters and what to avoid

Your passcode is the first line of defense if someone picks up your phone. It locks access to your messages, photos, payment information, and any apps that store sensitive data. A strong passcode is one that isn't obvious — avoid birthdays, sequential numbers like 1-2-3-4-5-6, or repeating digits like 1-1-1-1-1-1. If you use a custom alphanumeric code, mix uppercase and lowercase letters with numbers for extra security.

Write your passcode down and store it somewhere safe away from your phone — a notebook in a drawer, a password manager, or a trusted family member. If you forget it and don't have a backup, you'll have no choice but to erase your phone. That's why many people also set up Face ID or Touch ID as a faster unlock method — you still have your passcode as a backup if your face or fingerprint isn't recognized.

Changing your passcode on older iPhone models

On iPhones without Face ID (iPhone 8 and earlier), the process is nearly identical, except the menu is called "Touch ID & Passcode" instead of "Face ID & Passcode." Open Settings, scroll down, tap Touch ID & Passcode, enter your current passcode, and then tap "Change Passcode." The rest of the steps — entering your new code, confirming it, and choosing a format — work exactly the same way.

If you're using an iPhone so old it doesn't have Touch ID at all, the menu might straightforward say "Passcode" without any biometric option. The change process is still the same: Settings > Passcode > Change Passcode, then enter your current code and your new one.

Frequently Asked Questions

Can I change my passcode without entering my current one?

No. iPhone requires you to enter your current passcode before you can change it. This is a security feature to prevent someone else from changing your lock screen code if they gain temporary access to your phone. If you've forgotten your current passcode, you'll need to erase your iPhone and set it up again.

How often should I change my iPhone passcode?

There's no set rule, but changing it every few months is reasonable if you're concerned about security. If you think someone may have seen your code, change it right away. For most people, changing it once or twice a year is sufficient unless you suspect a breach.

Will changing my passcode affect my Face ID or Touch ID?

No. Your biometric data (your face or fingerprint) stays the same. Your passcode is a separate backup unlock method. Changing one does not affect the other. You'll still use Face ID or Touch ID to unlock your phone normally, and your passcode only comes into play if biometric unlock fails.

What if I change my passcode and then forget the new one when ready?

You'll need to erase your iPhone. There is no way to recover a forgotten passcode or reset it without erasing. This is why writing down your new passcode somewhere safe (not on your phone) is important right after you change it.

Can I use the same passcode I used before?

Yes. iPhone does not prevent you from reusing an old passcode. However, for security reasons, it's better to choose a new one each time you change it, especially if you think someone may have learned your old code.
