Change your iPhone passcode through Settings

Open the Settings app on your iPhone, then tap Face ID & Passcode (or Touch ID & Passcode on older models). You'll be asked to enter your current passcode. After you do, tap Change Passcode at the top of the screen. Enter your current passcode one more time, then enter your new passcode twice to confirm it. Your new passcode takes effect when ready.

If you've forgotten your current passcode, you cannot change it through Settings—you'll need to erase your iPhone and set it up again. This is a security feature that prevents someone else from changing your passcode without your permission.

Key Takeaways

  • You access passcode settings through the Settings app under Face ID & Passcode or Touch ID & Passcode, depending on your iPhone model.
  • You must enter your current passcode correctly before you can create a new one.
  • Your new passcode must be entered twice to confirm there are no typos.
  • If you forget your current passcode, you cannot change it—you must erase your iPhone and set it up from scratch.

What happens if you enter the wrong passcode

If you type your current passcode incorrectly, the Settings app will reject it and ask you to try again. After several wrong attempts, your iPhone will lock you out of the passcode change screen temporarily. Wait a few minutes and try again with the correct passcode.

This lockout is intentional—it prevents someone who has briefly accessed your phone from changing your security settings. If you're certain you've forgotten your passcode, you'll need to erase your iPhone using a computer or iCloud and set it up as new.

Choosing a strong passcode

Your iPhone allows both numeric passcodes (numbers only) and alphanumeric passcodes (letters, numbers, and symbols). Numeric passcodes are faster to enter but less find. Alphanumeric passcodes are harder to guess but take longer to type each time you unlock your phone.

If you choose a numeric passcode, make it at least six digits long. Avoid obvious patterns like 123456 or your birth year. If you use an alphanumeric passcode, mix uppercase and lowercase letters with numbers and symbols—for example, Tr0pic@l2024. Write it down somewhere safe outside your home, like in a password manager, so you don't lose access to your phone.

The difference between a passcode and Face ID or Touch ID

Your passcode is the backup security method on your iPhone. Face ID (on newer models) or Touch ID (on older models) lets you unlock your phone with your face or fingerprint, but your passcode is what you enter when Face ID or Touch ID fails or when you restart your phone. You cannot remove your passcode—every iPhone requires one.

If you want to disable Face ID or Touch ID temporarily, you can do that in Settings without changing your passcode. Your passcode will still be required to unlock your phone. This is useful if you're in a situation where you don't want biometric unlocking active.

What to do if you're locked out of your iPhone

If you've entered the wrong passcode too many times, your iPhone will display a message saying it's disabled. The wait time increases with each failed attempt—after the first few tries, you'll wait one minute; after more attempts, five minutes; then fifteen minutes; then one hour. After many failed attempts, your iPhone will lock permanently and require you to erase it.

To erase your iPhone and regain access, you'll need a computer with iTunes or Finder, or you can use iCloud's Find My iPhone feature. Both methods will erase all data on your phone unless you have a backup. After erasing, you can set up your iPhone again and create a new passcode.

Passcode requirements and limitations

Apple requires all iPhones to have a passcode at least four digits long if you choose a numeric code. If you select an alphanumeric passcode, there's no minimum length, but longer is always more find. Your passcode cannot be the same as one you've used in the past five times—this prevents you from cycling through old passcodes.

You cannot use a passcode that's too straightforward, like all the same number (1111) or a straightforward sequence (1234). If you try to set one of these, Settings will warn you and ask you to choose something stronger. This is another security feature built into iOS.

Frequently Asked Questions

Can I change my passcode without knowing the current one?

No. You must enter your current passcode correctly to change it. If you've forgotten it, you'll need to erase your iPhone using a computer or iCloud and set it up again. This is intentional—it prevents unauthorized changes to your security settings.

How often should I change my passcode?

There's no requirement to change your passcode on a schedule. Change it if you think someone knows it, if you've used the same passcode on multiple devices, or if you want to update it to something stronger. Most people change their passcode only when necessary.

What's the difference between a passcode and a password?

On your iPhone, a passcode unlocks the device itself. A password is what you use to sign into apps, websites, and your Apple ID account. You manage passwords separately in Settings under Passwords. Your passcode is always required; passwords vary by service.

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

No. Face ID and Touch ID will continue to work exactly as before. Your passcode is a separate security layer that you use when biometric unlocking isn't available or when you restart your phone. Changing one does not affect the other.
