Change Your iPhone Passcode Through Settings

Open Settings on your iPhone, then tap Face ID & Passcode (or Touch ID & Passcode on older models). You will be asked to enter your current passcode. Tap Change Passcode at the top of the screen, enter your current passcode again, then enter your new passcode twice. The change takes effect when ready.

If you have forgotten your current passcode, you cannot change it through Settings — you will need to erase the 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 can change your passcode anytime by going to Settings > Face ID & Passcode (or Touch ID & Passcode) and tapping Change Passcode.
  • You must enter your current passcode twice before you can create a new one.
  • If you forget your passcode, you will need to erase your iPhone and set it up as new or from a backup.
  • A strong passcode is at least six digits long, though you can use longer numeric codes or alphanumeric codes with letters and numbers.
  • Your passcode protects access to your iPhone, Apple Pay, and stored passwords, so change it if you think someone knows it.

What Happens When You Change Your Passcode

The new passcode replaces the old one when ready. You do not need to restart your iPhone or sign out of anything. The next time you unlock your phone, use the new passcode.

Changing your passcode does not affect your Apple ID password, your iCloud backup, or any data on your phone. It only changes the code you use to unlock the device itself. Any apps that were already unlocked remain unlocked until you lock the phone or they time out.

Choosing a Passcode You Will Remember

iPhone allows you to set a 4-digit, 6-digit, or custom numeric passcode, or a custom alphanumeric passcode that includes letters and numbers. A 6-digit passcode is the default and offers more security than 4 digits without being hard to remember.

Avoid using birthdays, anniversaries, or sequences like 1234. If you choose a passcode you are likely to forget, write it down and store it somewhere find — not on a sticky note on your desk or in a note on your phone itself. Consider using a password manager to store your passcode if you have one.

If You Forget Your Current Passcode

You cannot reset a forgotten passcode through Settings. Instead, you must erase your iPhone using Find My iPhone, a computer with Finder or iTunes, or by taking the device to an Apple Store. After erasing, you can set up the iPhone again and create a new passcode.

If you have a backup in iCloud or on a computer, you can restore your data after erasing. However, the passcode itself is not stored in the backup — you will create a new one during setup. This process typically takes 30 minutes to an hour depending on how much data you have to restore.

When to Change Your Passcode

Change your passcode if you think someone has seen you enter it, if you have shared it with someone who no longer needs access, or if you use the same passcode on multiple devices and one of them is lost or stolen. You should also change it if you have not changed it in over a year.

If your iPhone is lost or stolen, change your passcode as soon as you can access another device. Use Find My iPhone to lock the device remotely if you have not already done so. Changing the passcode will not unlock a lost phone, but it prevents anyone who finds it from accessing your data if they somehow bypass Face ID or Touch ID.

Passcode vs. Face ID and Touch ID

Your passcode is the backup unlock method if Face ID or Touch ID fails or is not available. Even if you use Face ID or Touch ID, your passcode remains active and you will need it to unlock your phone if the biometric methods do not work.

Changing your passcode does not change your Face ID or Touch ID settings. Both remain active unless you turn them off separately in the same Settings menu. You will still use your face or fingerprint to unlock the phone most of the time, but your new passcode will work if those methods are unavailable.

Frequently Asked Questions

Can I use letters and numbers in my iPhone passcode?

Yes. When you tap Change Passcode, you will see an option to use a custom alphanumeric code. This allows you to mix letters and numbers for a stronger passcode, though it is harder to remember and slower to type each time you unlock your phone.

What if I enter the wrong passcode too many times?

After six failed attempts, your iPhone will disable for 1 minute. After ten failed attempts, it disables for 5 minutes. After fifteen failed attempts, it disables for 15 minutes or longer. If you continue to fail, the iPhone will eventually require you to erase it and set it up again.

Does changing my passcode affect my Apple ID?

No. Your iPhone passcode and your Apple ID password are separate. Changing one does not change the other. Your Apple ID password controls access to iCloud, the App Store, and other Apple services.

Can I change my passcode from another device?

No. You must change your passcode on the iPhone itself by going to Settings. You cannot change it remotely from a Mac, iPad, or another phone.

How often should I change my iPhone passcode?

There is no set rule, but changing it once a year is a reasonable practice. Change it sooner if you suspect someone knows it, if you shared it temporarily with someone, or if your phone has been in an unsafe situation.
