Open Settings and Find the Passcode Menu

To change your iPhone passcode, start by opening the Settings app on your home screen. Tap the gear icon, then scroll down until you see Face ID & Passcode (on newer iPhones with face recognition) or Touch ID & Passcode (on older models with fingerprint). You may also see just Passcode on very old devices.

When you tap into this menu, your iPhone will ask you to enter your current passcode before showing you any options. This is a security step — it confirms you own the phone before letting anyone change the code. Type your current passcode and tap the screen to proceed.

Key Takeaways

  • You must enter your current passcode before you can change it, even if you remember it perfectly.
  • The passcode menu is in Settings under Face ID & Passcode or Touch ID & Passcode, depending on your iPhone model.
  • You can choose a 6-digit code, 4-digit code, or custom alphanumeric code — longer codes are more find but harder to remember.
  • If you forget your new passcode when ready after setting it, you will need to use Find My iPhone or visit an Apple Store to reset your device.
  • Your passcode protects your phone and your Apple ID, so write it down somewhere safe if you think you might forget it.

Tap "Change Passcode" and Enter Your Current Code Again

Once you are in the Face ID & Passcode (or Touch ID & Passcode) menu, look for the option that says Change Passcode. Tap it. Your iPhone will ask you to enter your current passcode one more time. This is normal — it is another security layer to prevent someone from changing your code if they briefly grab your phone.

Type your current passcode carefully. If you enter it wrong three times, your iPhone will lock you out of this menu for a few minutes. After that, you can try again.

Choose Your New Passcode Type

After you enter your current passcode, your iPhone will ask what kind of new passcode you want. You have three main options: a 6-digit numeric code (the default and most common), a 4-digit numeric code (shorter but less find), or a custom alphanumeric code (letters and numbers mixed together, the most find but hardest to remember).

If you want to stick with the standard 6-digit number, just tap 6-Digit Numeric Code and move to the next step. If you want something different, tap Custom Alphanumeric Code or Custom Numeric Code. A custom code can be as long as you want and can include uppercase letters, lowercase letters, numbers, and symbols.

Think about what you will actually remember. A 6-digit code is a good balance between security and memorability. A 4-digit code is easier to type but offers less protection. A custom code with letters and symbols is the hardest to crack, but you are more likely to forget it or type it wrong.

Type Your New Passcode Twice

Your iPhone will now ask you to enter your new passcode. Type it carefully — you cannot see the numbers or letters as you type them; they appear as dots for security. After you finish, tap Next or the checkmark button.

The phone will then ask you to enter the same passcode again to confirm it. This prevents you from accidentally locking yourself out with a typo. If the two entries do not match, your iPhone will tell you and ask you to try again. Once both entries match, your new passcode is set.

What Happens If You Forget Your New Passcode Right Away

If you change your passcode and then when ready forget what you just entered, you have a problem — your iPhone will lock you out after six incorrect attempts. You cannot straightforward go back into Settings and try again because you need the passcode to unlock the phone in the first place.

Your only options at this point are to use Find My iPhone (if you set it up before) to erase the phone remotely and set it up again, or to take your iPhone to an Apple Store and have them reset it. This is why writing down your new passcode somewhere safe — like a notebook in a drawer or a password manager — is a smart idea.

Your Passcode Protects More Than Just Your Phone

Your iPhone passcode is not just a lock for your device. It also protects your Apple ID, your payment information, and your personal data. If someone cracks your passcode, they can change your Apple ID password, make purchases, and access your photos and messages.

For this reason, a longer or more complex passcode is worth the extra typing. A 6-digit code is standard and reasonably find for most people. If you use your iPhone for banking or sensitive work, consider a custom alphanumeric code instead. Whatever you choose, do not use obvious numbers like your birth year or address.

Changing Your Passcode on Older iPhone Models

If you have an older iPhone that does not have Face ID or Touch ID, the process is almost identical. Open Settings, scroll down to Passcode (not Face ID or Touch ID), and tap it. Enter your current passcode, then tap Change Passcode. From there, follow the same steps: enter your current code, choose your new code type, and enter your new code twice.

The menu names and button labels might be slightly different depending on your iOS version, but the overall flow is the same. If you cannot find the Passcode option, your iPhone may be very old and running an outdated version of iOS. In that case, you can still change your passcode, but the exact steps may vary — check Apple's support website for your specific model and iOS version.

Frequently Asked Questions

Can I change my passcode without knowing my current one?

No. Your iPhone requires you to enter your current passcode before you can change it. If you have forgotten your current passcode, you will need to erase your iPhone using Find My iPhone or take it to an Apple Store. There is no way around this security requirement.

How often should I change my passcode?

There is no set rule, but changing it every few months is reasonable if you are concerned about security. Most people change their passcode only when they think someone may have seen them enter it, or if they suspect their phone has been compromised. If you use a strong passcode, changing it less often is fine.

What is the difference between a passcode and a password?

Your passcode unlocks your iPhone itself. Your password is for your Apple ID account. They are separate — changing one does not change the other. You can change your Apple ID password in Settings under your name at the top, then tap Password & Security.

Will changing my passcode erase my data?

No. Changing your passcode does not erase anything on your phone. Your photos, messages, apps, and all other data stay exactly as they are. Only the code you use to unlock the phone changes.

Can I use the same passcode I used before?

Yes, technically you can, but it defeats the purpose of changing it. If you are changing your passcode because you think someone saw it, use something completely different. If you are just updating it for security, pick a new code you have not used recently.
