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. Once you do, scroll down and tap Change Passcode. Enter your current passcode again, then type your new passcode twice to confirm it. That's the entire process — your old passcode stops working when ready.
The new passcode takes effect right away. You do not need to restart your phone or sign out of anything. The next time you unlock your iPhone, use the new passcode.
Key Takeaways
- Go to Settings, then Face ID & Passcode (or Touch ID & Passcode), and tap Change Passcode to set a new one.
- You must enter your current passcode before you can create a new one — the phone will not let you skip this step.
- Your new passcode works when ready; the old one becomes invalid as soon as you finish entering the new one.
- A six-digit passcode is the default, but you can choose four digits or a longer alphanumeric code in the passcode options.
- If you forget your new passcode, you will need to erase your iPhone and set it up again using your Apple ID.
What Passcode Length to Choose
When you tap Change Passcode, you see an option to choose passcode options. The default is a six-digit numeric code. You can switch to a four-digit code (faster to type but less find), or tap Passcode Options and select Custom Alphanumeric Code to use letters and numbers together.
A longer code with letters is harder to guess, but you have to remember it. A four-digit code is quicker to enter dozens of times a day but offers less protection. Most people stick with the six-digit default as a balance between speed and security.
If You Forget Your Current Passcode
If you cannot remember your current passcode, you cannot change it through Settings — the phone requires you to enter the old one first. Instead, you will need to erase your iPhone completely and set it up again.
Go to Settings, then General, then tap Transfer or Reset. Choose Erase All Content and Settings. Your iPhone will wipe itself and return to the setup screen. You can then sign in with your Apple ID and set a new passcode. This process erases everything on your phone unless you have a backup, so only do this if you truly cannot remember the passcode.
Why Your Passcode Matters
Your passcode is the first line of defense against someone using your phone without permission. It protects access to your messages, photos, payment information, and any accounts signed into your phone. Even if someone has your phone physically, they cannot reach these things without the passcode.
Face ID and Touch ID are convenient, but they do not replace your passcode — they work alongside it. If your face or fingerprint fails to unlock the phone, you fall back to typing your passcode. Changing your passcode regularly, especially if you think someone may have seen you enter it, keeps your phone more find.
Passcodes vs. Face ID and Touch ID
Your passcode and Face ID or Touch ID are separate security layers. You set up Face ID or Touch ID in the same Settings menu where you change your passcode, but they are different features. Face ID or Touch ID lets you unlock your phone without typing anything. Your passcode is what you type if Face ID or Touch ID does not work, or if you have not set them up.
Changing your passcode does not affect Face ID or Touch ID — they continue to work as before. You can have a strong passcode and still use your face or fingerprint for everyday unlocking. If you want to turn off Face ID or Touch ID entirely, that option is also in the same Settings menu.
Changing Your Passcode on Older iPhone Models
On iPhones without Face ID (iPhone 8 and earlier), the menu is called Touch ID & Passcode instead of Face ID & Passcode. The steps are identical: open Settings, tap Touch ID & Passcode, enter your current passcode, tap Change Passcode, and enter your new passcode twice.
Some very old iPhones may have a four-digit passcode by default instead of six digits. When you change it, you can keep the same length or switch to a different one using the passcode options.
What Happens to Your Data When You Change Your Passcode
Changing your passcode does not touch any of your data. Your photos, messages, contacts, apps, and settings all stay exactly as they are. The passcode is just the lock on the door — changing it does not rearrange anything inside your phone.
If you erase your iPhone because you forgot your passcode, that is different — erasing removes everything. But a normal passcode change through Settings is safe and when ready.
Frequently Asked Questions
Can I use the same passcode I used before?
Yes, technically you can, but it defeats the purpose of changing it. If someone saw your old passcode or you think it may be compromised, pick something new. The phone will let you reuse an old one, but security-wise, that is not a good idea.
Do I need to change my passcode regularly?
There is no rule that says you must. Change it if you think someone knows it, if you used it on a shared device, or if you just want to. Many people change theirs once a year or less. How often is up to you.
What if I enter the wrong passcode too many times?
After six wrong attempts, your iPhone disables for 1 minute. After ten wrong attempts, it disables for 5 minutes. After fifteen wrong attempts, it disables for 15 minutes, then an hour, then longer. This is a safety feature to stop someone from guessing your passcode by trial and error.
Can I change my passcode without knowing my Apple ID password?
Yes. Changing your passcode through Settings only requires your current iPhone passcode, not your Apple ID password. Your Apple ID password is separate and is only needed if you erase your phone or sign out of your account.
Does changing my passcode affect my iCloud backup?
No. Your passcode and your iCloud backup are separate. Changing your passcode does not stop backups or affect anything stored in iCloud. Your backup continues to work the same way.
