You're standing in line at the grocery store. Someone is hovering a bit too close behind you while you tap in that four-digit code you’ve used since 2014. It feels sketchy. Or maybe you just realized your toddler has memorized your passcode and is currently attempting to buy $400 worth of "gems" in a mobile game. Whatever the reason, you've decided it’s time to change things up.
Security is weird because we don't think about it until we feel exposed.
When people talk about how to change PIN in iPhone, they usually mean the passcode—that string of numbers that guards your photos, bank apps, and private texts. Apple calls it a passcode, but most of us just call it a PIN. It’s the gatekeeper. If someone has that, they basically have your life.
Finding the Right Menu
Apple loves to hide things in plain sight. Depending on which iPhone you're clutching right now, the menu you need has a slightly different name. If you have a modern phone with a notch or a "Dynamic Island" at the top, you’re looking for Face ID & Passcode. If you’re rocking an older model with a physical home button—bless your heart, those things are tanks—you’ll see Touch ID & Passcode.

Open your Settings app. It's the one that looks like a bunch of grey gears. Scroll down. It’s usually buried just below "General" and "Control Center."
Once you tap into that menu, your phone is going to challenge you immediately. It wants your current code. This is the first hurdle. If you don't know the current one, you're in for a much longer day involving a computer and a full device reset, because Apple takes the "encrypted" part of their branding very seriously.
The Actual Switch
Inside the Face ID & Passcode section, scroll past all the toggles for "iPhone Unlock" and "Apple Pay." Look for the blue text that says Change Passcode.
Tap it.
Now, pay attention here because this is where people trip up. You have to enter your old code again. Then, the screen asks for a new one. But wait. Before you just punch in six digits, look at the bottom of the screen for the small, blue link that says Passcode Options.
This is the "secret" menu.
You aren't stuck with just six numbers. You've actually got choices:
- Custom Alphanumeric Code: This is basically a full-blown password with letters and symbols. It’s the most secure but a total pain to type while you're walking.
- Custom Numeric Code: This allows you to make a PIN that is as long as you want. Want an 11-digit PIN? Go for it.
- 4-Digit Numeric Code: The old school way. It's less secure—only 10,000 possible combinations—but it's fast.
Honestly, if you use Face ID most of the time, choosing a longer numeric code is a smart move. You rarely have to type it, but it makes your phone significantly harder to crack for a random thief.
Why Changing Your PIN Frequently Matters More Than You Think
We treat our phones like digital appendages. We take them to the bathroom, to bed, and to every meeting. Because of that, the screen often develops "smudge patterns." If you use the same 4-digit PIN for three years, a thief doesn't even need to watch you type it; they can just tilt your phone in the light and see which four spots on the glass are the most worn down or oily.

Gross, but true.
Changing the sequence forces you to clean the slate, literally and figuratively.
The Stolen Device Protection Factor
In early 2024, Apple pushed out a massive update called Stolen Device Protection. If you haven't turned this on, stop what you're doing and do it now. It’s located in the same menu where you go to change your PIN.
Why does this matter? Well, if a thief sees you type your PIN in a bar and then swipes your phone, they used to be able to immediately change your Apple ID password and lock you out of your own life.
With Stolen Device Protection on, the phone uses "Location Awareness." If you aren't at home or work, the phone will require Face ID twice with a one-hour delay between them before it allows anyone to change the passcode or the Apple ID settings. It’s a literal lifesaver for your data.
Common Myths About iPhone Passcodes
There’s a lot of bad info out there. Some people think that if they change their PIN, they’ll lose their Face ID data. That's wrong. Your face or fingerprint is stored in a separate "Secure Enclave" chip. Changing the numerical code doesn't delete your facial map.
Another common fear is that changing the PIN will mess up Apple Pay. Again, nope. Your cards stay in the Wallet; you might just be asked to verify your identity once after the change to make sure it’s actually you.
What is true is that if you change your PIN and then immediately forget it, there is no "Forgot Password" link for the lock screen. Apple cannot see your passcode. They can't reset it for you at the Genius Bar. If it's gone, your only option is to wipe the phone and restore from an iCloud backup.
Choosing a "Strong" PIN
"123456" is bad.
"000000" is worse.
Your birthday? Everyone knows it.
The year you graduated? It’s on your LinkedIn.
Try using a significant date that isn't yours. Maybe the day your favorite obscure movie was released, or the house number of your childhood home. Just avoid patterns. The human brain loves patterns, but so do the algorithms used by people trying to break into devices.
What if the "Change Passcode" Option is Greyed Out?
Sometimes you go into the settings and you can't even tap "Change Passcode." It’s frustrating. This usually happens for two reasons.
First, Screen Time. If you have "Content & Privacy Restrictions" turned on under the Screen Time menu, you might have blocked passcode changes. Go to Settings > Screen Time > Content & Privacy Restrictions and make sure "Passcode Changes" is set to "Allow."
Second, work emails. If you have a corporate email account (like Microsoft Outlook for work) synced to your iPhone, your boss might have installed a "Configuration Profile." Companies often force users to have a 6-digit PIN instead of a 4-digit one. If your work requires it, you can't change the complexity, though you can still change the numbers.
Keeping Your Data Safe Beyond the PIN
Once you've figured out how to change PIN in iPhone, don't stop there. Security is a layer cake.
- Check your Emergency SOS settings. Make sure "Call with Hold and Release" is on.
- Clean your screen. Seriously. Get those smudges off so your new pattern isn't visible.
- Review your iCloud Backup. Ensure it's running nightly. If you ever do get locked out because you forgot your new PIN, that backup is the only thing standing between you and total data loss.
It's a quick process. Five minutes, tops. But it's the difference between a minor inconvenience and a total identity theft nightmare.

Start by opening your Settings and navigating to Face ID & Passcode. Update your PIN to a 6-digit sequence that doesn't involve your birth year or consecutive numbers. While you're in that menu, scroll down and ensure Stolen Device Protection is toggled to On. Once you've confirmed the change, take a moment to restart your phone; this forces the system to require the new PIN immediately, ensuring it "sticks" in your muscle memory.
