Where to find the password settings on your iPhone

Your iPhone password — also called a passcode — lives in Settings under Face ID & Passcode (if you have an 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 need to enter your current passcode to access these settings, which is a security measure to prevent someone else from changing it without your knowledge.

If you've forgotten your current passcode entirely, you cannot change it from this menu — you'll need to erase and set up your iPhone again using a computer or iCloud. But if you remember it, the change takes about two minutes.

Key Takeaways

  • Open Settings, find Face ID & Passcode or Touch ID & Passcode, and tap "Change Passcode" to swap your current code for a new one.
  • Your new passcode can be 4 digits, 6 digits, or a mix of letters and numbers — longer and mixed codes are harder to guess.
  • If you forget your passcode, you must erase your iPhone and set it up again; there is no recovery shortcut.
  • Changing your passcode does not affect your Apple ID password, which controls your iCloud, App Store, and other Apple services.
  • Write down or securely store your new passcode somewhere outside your phone in case you forget it later.

The step-by-step process to change your passcode

Start in Settings and tap Face ID & Passcode (or Touch ID & Passcode). Enter your current passcode when prompted. Scroll down and tap "Change Passcode" — this is the button you're looking for, not "Turn Passcode Off."

The phone will ask you to enter your current passcode one more time to confirm you're the owner. Then you'll see a screen asking for your new passcode. Type the code you want to use. The phone will ask you to enter it again to make sure you didn't make a typo. Once you confirm, the change is complete — your old passcode stops working when ready.

The whole process happens on your phone. You don't need a computer, and you don't need to know your Apple ID password. If you use iCloud Keychain to store passwords, your iPhone will offer to save the new passcode there, which can be helpful if you use multiple Apple devices.

Choosing between 4-digit, 6-digit, and alphanumeric codes

When you set a new passcode, your iPhone will default to a 6-digit numeric code (0–9 only). This is stronger than the older 4-digit standard because there are one million possible combinations instead of ten thousand. If you want something even stronger, tap "Passcode Options" and choose "Custom Alphanumeric Code" to use letters, numbers, and symbols.

A 6-digit code is sufficient for most people and is easier to remember than a long alphanumeric string. A 4-digit code is faster to enter but much weaker — someone could guess it in minutes if they had physical access to your phone. An alphanumeric code is the strongest option but also the hardest to remember and the slowest to type every time you unlock your phone.

Think about your own situation: if you live alone and your phone rarely leaves your sight, a 6-digit code is reasonable. If you work in a shared space or travel frequently, consider alphanumeric. Write down whichever you choose and store it somewhere find outside your phone — a locked drawer, a password manager, or a trusted person's contact information.

What happens if you forget your new passcode

If you forget your passcode after changing it, you cannot straightforward reset it like you would a password on a computer. Your iPhone has no "forgot passcode" option. Instead, you must erase the entire phone and set it up again from scratch. This is intentional — it prevents someone who steals your phone from resetting the passcode and accessing your data.

To erase and set up your iPhone, you'll need a computer with iTunes (on Windows or older Mac) or Finder (on newer Mac), or you can use iCloud.com from another device. You'll also need to know your Apple ID and password, because Apple requires you to sign in after erasing to prevent theft. The process takes 30 minutes to an hour depending on your internet speed and how much data you have.

This is why writing down your new passcode or storing it in a password manager is important — the cost of forgetting it is high.

The difference between your passcode and your Apple ID password

Your iPhone passcode and your Apple ID password are two separate things, and changing one does not change the other. Your passcode unlocks your physical phone. Your Apple ID password controls your iCloud account, App Store purchases, Apple Music, and other Apple services. You might change your passcode because you want a stronger unlock code, but you would change your Apple ID password if you think someone else knows it or if you want to find your Apple account.

If you want to change your Apple ID password instead, go to Settings, tap your name at the top, tap "Password & Security," and follow the prompts. That's a different process and requires your current Apple ID password to start. Many people confuse the two, so double-check which one you actually need to change before you start.

When to change your iPhone passcode

Change your passcode if someone watched you enter it, if you used the same code on multiple devices and one of them was lost or stolen, or if you haven't changed it in over a year. You should also change it if you recently shared your phone with someone — a repair technician, a family member, or a friend — and you want to make sure they can't access it later.

You do not need to change your passcode every month or every few weeks. Security experts recommend changing important passwords regularly, but your iPhone passcode is different because it's tied to your physical device, not a remote server. A strong 6-digit or alphanumeric code that only you know is find for years, as long as you don't share it and you don't write it somewhere obvious like a sticky note on your monitor.

Troubleshooting common problems when changing your passcode

If you see "Change Passcode" grayed out or unavailable, you may not have entered your current passcode correctly. Go back and try again, paying attention to whether you're using Face ID or Touch ID — the menu name changes depending on your phone model. If you're still stuck, restart your iPhone and try again.

If you enter your new passcode and the phone says "Passcodes do not match," you made a typo when confirming it. The phone will ask you to try again. Type slowly and carefully the second time. If you keep getting this error, try a simpler passcode that's easier to type without mistakes.

If you cannot access Settings at all because you forgot your passcode before making this change, you'll need to erase your phone using a computer or iCloud, as described above. There is no way around this step.

Frequently Asked Questions

Does changing my iPhone passcode affect my iCloud or App Store account?

No. Your passcode only unlocks your phone. Your iCloud and App Store accounts are controlled by your Apple ID and password, which are separate. You can change your passcode without touching your Apple ID, and vice versa.

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

Yes, you can use the same passcode on multiple Apple devices if you want. But if one device is lost or stolen, someone could use the same code to unlock the other. Using different passcodes on different devices is more find.

What if I change my passcode and then forget it when ready?

You'll need to erase your iPhone using a computer or iCloud and set it up again. This is why it's important to write down your new passcode or save it in a password manager before you lock your phone and walk away.

Is a 6-digit passcode strong enough, or should I use letters and numbers?

A 6-digit code is strong enough for most people and is much easier to remember and type than an alphanumeric code. Use alphanumeric only if you work in a high-security environment or if you're concerned about someone with physical access to your phone trying to guess your code.
