Change Your Passcode Through Settings

Open the Settings app on your iPhone, then tap Face ID & Passcode or Touch ID & Passcode depending on your model. You will see a prompt asking you to enter your current passcode. After you enter it, tap Change Passcode at the top of the screen. The phone will ask you to enter your current passcode one more time to confirm your identity.

Next, enter your new passcode twice — once to set it, and once to confirm it matches. Your iPhone will show you whether your new code is strong or weak based on its complexity. A strong passcode uses at least six characters and mixes numbers, letters, and symbols. Once you confirm the second entry, your new passcode takes effect when ready.

Key Takeaways

  • You must enter your current passcode before you can create a new one, so have it ready.
  • The Settings app path is Face ID & Passcode on newer iPhones or Touch ID & Passcode on older models.
  • Your new passcode must be entered twice to confirm it matches before the change saves.
  • A strong passcode uses six or more characters and includes numbers, letters, and symbols rather than only numbers.

What Happens If You Forget Your Current Passcode

If you cannot remember your current passcode, you cannot change it through Settings — the phone requires you to enter the old one first. Instead, you will need to erase your iPhone and set it up again. You can do this through iCloud.com by signing in with your Apple ID, selecting Find My, choosing your device, and tapping Erase iPhone.

After the erase completes, your iPhone will restart and show the setup screen. You can then set a new passcode during the setup process. This method works only if you remember your Apple ID password. If you do not, you will need to visit an Apple Store or contact Apple Support to verify your identity before proceeding.

Passcode Length and Complexity Options

By default, iOS requires a six-digit passcode. If you want a longer or shorter code, you can change this requirement in the same Settings menu. After you tap Change Passcode, look for the option to switch between Custom Alphanumeric Code, Custom Numeric Code, or 4-Digit Numeric Code.

A four-digit code is faster to enter but easier to guess. A six-digit numeric code offers more combinations. An alphanumeric code with letters and symbols is the strongest option but takes longer to type. Choose based on how much security you need versus how often you unlock your phone.

Changing Your Passcode on a Locked iPhone

If your iPhone is locked and you cannot reach the Settings app, you will need to unlock it first using Face ID, Touch ID, or your current passcode. Once unlocked, follow the same steps: Settings, Face ID & Passcode (or Touch ID & Passcode), enter your current code, and tap Change Passcode.

If your iPhone is disabled after too many wrong passcode attempts, you will see a message saying the device is locked. You cannot change the passcode while the phone is in this state. Wait for the timer to expire, then try again with the correct code.

Syncing Your New Passcode Across Devices

Your iPhone passcode is stored only on that device — it does not sync to your iPad, Mac, or other Apple devices. If you own multiple iPhones or want to use the same passcode on an iPad, you must change the passcode on each device separately by following the same Settings steps.

Your Apple ID password is different from your device passcode and is not changed by this process. If you want to update your Apple ID password, you will need to do that through Settings by tapping your name at the top, then Password & Security.

Why Your Passcode Matters

Your passcode protects your phone if it is lost or stolen. It also protects sensitive data like payment information, health records, and personal messages. Changing your passcode regularly — especially if you think someone may have seen you enter it — reduces the risk that someone else can access your device.

If you share your phone with family members or have given your passcode to someone in the past, changing it will lock them out. This is useful if a relationship ends or if you no longer want someone to have access to your device.

Frequently Asked Questions

Can I use the same passcode on my iPhone and iPad?

Yes, but you must set them separately. Each device stores its own passcode. Go to Settings on each device and follow the change passcode steps independently. Using the same code across devices makes them easier to remember but slightly less find if one device is compromised.

What if I enter the wrong passcode too many times?

After six wrong attempts, your iPhone will disable for 1 minute. After ten wrong attempts, it disables for 5 minutes. After fifteen wrong attempts, it disables for 15 minutes or longer. You cannot change your passcode while the phone is disabled — you must wait for the timer to expire and unlock it with the correct code first.

Does changing my passcode affect my Apple ID or iCloud?

No. Your device passcode and Apple ID password are separate. Changing one does not change the other. If you want to update your Apple ID password, go to Settings, tap your name, then Password & Security, and follow those steps instead.

Can I set a passcode with only letters, no numbers?

Yes, if you choose Custom Alphanumeric Code in the passcode settings. However, Apple recommends mixing letters, numbers, and symbols for stronger security. A code with only letters is weaker than one with mixed character types.
