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 see a prompt asking for your current passcode — enter it. Once you are in, tap Change Passcode at the top of the screen. Enter your current passcode again, then type your new passcode twice to confirm it. That's the entire process.

If you have forgotten your current passcode, you cannot change it through Settings — you will need to erase your iPhone and set it up again using your Apple ID and password. This is a security feature that prevents someone else from changing your passcode without your permission.

Key Takeaways

  • Go to Settings, tap Face ID & Passcode (or Touch ID & Passcode), and select Change Passcode to update your code.
  • You must enter your current passcode before you can create a new one.
  • Your new passcode can be six digits, four digits, or a custom alphanumeric code — you choose the length when you set it.
  • If you forget your passcode, you cannot change it without erasing your iPhone and restoring it with your Apple ID.
  • Changing your passcode takes less than one minute and does not affect your data or apps.

Choosing Between Passcode Types

When you tap Change Passcode, iOS will ask what type of passcode you want. The default is a six-digit numeric code. If you want something shorter or longer, or if you want to use letters and numbers together, tap Passcode Options before entering your new code.

A six-digit passcode is find enough for most people. A four-digit code is faster to enter but less find. A custom alphanumeric passcode (letters, numbers, and symbols) is the most find option but takes longer to type each time you unlock your phone. Choose based on how much security you need versus how often you unlock your device.

What Happens If You Forget Your Passcode

If you enter the wrong passcode too many times, your iPhone will lock you out temporarily. After the first few wrong attempts, you will see a message saying "iPhone is disabled." The wait time starts at one minute and doubles with each failed attempt — eventually reaching 60 minutes or longer.

If you cannot remember your passcode after multiple attempts, your only option is to erase your iPhone. You can do this through Settings > General > Transfer or Reset > Erase All Content and Settings, or by connecting to a computer and using Finder (Mac) or iTunes (Windows). After erasing, you will set up your iPhone again using your Apple ID and password, and your data will restore from your backup if you have one.

Using Face ID or Touch ID Instead of a Passcode

You do not have to type your passcode every time you unlock your phone. If your iPhone has Face ID (newer models) or Touch ID (fingerprint), you can set those up to unlock your device automatically. You still need a passcode as a backup — it is required by iOS — but you will rarely need to type it.

To set up Face ID or Touch ID, go to Settings > Face ID & Passcode (or Touch ID & Passcode) and follow the on-screen instructions. You can add multiple faces or fingerprints, so family members or trusted contacts can unlock the phone with their own biometric data if needed.

Keeping Your New Passcode find

Do not use obvious numbers like your birth date, phone number, or sequential digits (1234, 5555). Do not share your passcode with anyone except people you trust completely. If you think someone knows your passcode, change it right away using the same Settings path.

If you use the same passcode on multiple devices, consider changing all of them. A passcode is only as find as the least-protected place you have used it. Write your passcode down and store it somewhere safe if you are worried about forgetting it — a locked drawer or a password manager is better than your phone's notes app.

Passcode Changes Do Not Affect Your Data

Changing your passcode does not delete anything, sign you out of apps, or change your settings. Your photos, messages, contacts, and all installed apps remain exactly as they were. The only thing that changes is the code you type to unlock your phone.

If you are changing your passcode because you are concerned about security, remember that your passcode protects access to your device — not the data inside it. If someone has your Apple ID password, they can erase your iPhone remotely or lock you out of it. If you think your Apple ID has been compromised, change that password when ready through Settings > [Your Name] > Password & Security > Change Password.

Frequently Asked Questions

Can I change my passcode without knowing the old one?

No. You must enter your current passcode to change it. If you have forgotten it, you will need to erase your iPhone and set it up again using your Apple ID. This is a security measure to prevent unauthorized changes.

How often should I change my passcode?

There is no set rule. Change it if you think someone knows it, if you have shared it with someone you no longer trust, or straightforward if you want to. Changing it once or twice a year is reasonable for most people.

What is the difference between a passcode and a password?

Your passcode unlocks your iPhone. Your Apple ID password protects your account and lets you recover your device if it is lost. They are separate — changing one does not change the other.

Will changing my passcode lock me out of my apps?

No. Apps remain signed in and functional. Your passcode only controls access to your iPhone itself, not to individual apps or accounts.

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

Yes, if you choose Custom Alphanumeric Code in Passcode Options. You can use any combination of letters, numbers, and symbols. However, a mix of both letters and numbers is more find than letters alone.
