You’re staring at your screen, and suddenly it hits you. Maybe you saw someone glance over your shoulder while you were typing in those six digits at the coffee shop. Perhaps you just realized your "super secret" code is actually your birthday, and honestly, that’s a security disaster waiting to happen. Whatever the reason, you need to know how to change password on your iphone, and you need to do it before you forget or get distracted by a TikTok notification.
It's one of those things we all assume we know how to do until we’re actually digging through the Settings app and realize Apple has moved things around—again.
Most people think a passcode is just a barrier for thieves. It’s not. It’s the literal encryption key for your entire digital life. Your banking apps, your private photos, that one note where you keep all your other passwords—all of it is wrapped up in that one code. If you’re still using "000000" or "123456," you aren't just being lazy; you're leaving the front door to your identity wide open.
The Actual Steps to Change Password on Your iPhone
First off, let's get the terminology straight. Apple officially calls it a "Passcode," not a password, though everyone uses the terms interchangeably.
Grab your phone. Open Settings. You’re going to scroll down until you see a red icon that says Face ID & Passcode (or Touch ID & Passcode if you’re rocking an older model like the SE). It’s nestled right between "Siri & Search" and "Emergency SOS."

Once you tap that, your iPhone is going to demand your current passcode. This is the first hurdle. If you don't know the current one, you're looking at a full device reset, which is a whole different headache involving iCloud backups and a lot of patience.
After you’re in, ignore the sea of toggles for a second. Scroll down past the middle of the screen. You’ll see a blue link that says Change Passcode. Tap it.
Now, the iPhone asks for the old one again. Think of it as a "are you really you?" check. Then, you’ll be prompted to enter a new one. Wait! Before you just punch in six numbers, look at the bottom. There’s a tiny option called Passcode Options. This is where the real security happens. You can choose between a 4-digit numeric code (don't do this), a 6-digit numeric code, or—my personal favorite—a Custom Alphanumeric Code.
Why the Alphanumeric Option is the Secret Winner
Most users stick to the standard six digits because it’s fast. I get it. We unlock our phones roughly 80 to 100 times a day. But if you choose the custom alphanumeric option, you can create a password that includes letters and symbols.
Think about the math. A 4-digit code has 10,000 possible combinations. A 6-digit code has a million. That sounds like a lot, right? It isn't. A specialized "Brute Force" box can crack a 6-digit numeric code in minutes if the software bypasses Apple's lockout delays.
But a complex password? That’s a different beast entirely.
If you use a mix of uppercase letters, numbers, and a symbol, the time it takes to crack that goes from minutes to centuries. Even if you use Face ID for 99% of your unlocks, having that complex "backdoor" password makes your encrypted data significantly safer from sophisticated attacks.
The "Stolen Device Protection" Reality Check
In early 2024, Apple introduced something called Stolen Device Protection. If you haven't turned this on yet while you're in the passcode settings, stop what you're doing and do it now.
Why? Because there was a massive wave of thefts where criminals would watch people type their passcodes in public bars or trains, then steal the physical phone. With just that passcode, they could change the Apple ID password, turn off "Find My," and literally lock the owner out of their own life.
With Stolen Device Protection active, the iPhone requires Face ID or Touch ID for sensitive actions when you're away from "familiar locations" like your home or office. If the thief tries to change the passcode or Apple ID, the phone forces a one-hour security delay. It’s a literal lifesaver. It’s basically the "anti-shoulder-surfing" insurance policy.
Common Pitfalls and Memory Fails
We’ve all been there. You change your passcode at 11:00 PM because you're feeling productive, wake up at 7:00 AM, and realize your brain has completely purged the new sequence.
Apple used to have a "grace period" for this. In recent iOS versions, if you change your passcode, you can actually use your old passcode to reset it for up to 72 hours if you forget the new one. This is tucked away in the "Passcode Reset" options that appear after a few failed attempts.
However, don't rely on this. Write the new code down on a physical piece of paper and put it in a drawer for a few days until the muscle memory kicks in. Do not save it in a "Note" on the same phone. That’s like locking your car keys inside the car.
What About Face ID and Touch ID?
Changing your passcode doesn't necessarily delete your Face ID or Touch ID data, but it does act as the primary key. If your phone restarts, or if you don't use it for 48 hours, the biometric sensors won't work. You must enter the passcode.
Also, a little-known fact: if you’re ever in a situation where you don't want someone to force you to unlock your phone with your face, you can quickly press the power button and either volume button simultaneously. This "disables" biometrics instantly and forces a passcode entry. Knowing how to change password on your iphone is only half the battle; knowing how to manage the "gate" is the rest.
Troubleshooting the "Greyed Out" Settings
Sometimes, you’ll go to the settings and find that the "Change Passcode" option is greyed out. It’s annoying. You can tap it a thousand times and nothing happens.
Usually, this is because of a "Configuration Profile." If your iPhone is a work phone, your IT department might have installed a profile that forces a certain password complexity or prevents you from changing it. You can check this in Settings > General > VPN & Device Management.
Another culprit? Screen Time. If you have "Content & Privacy Restrictions" turned on under the Screen Time settings, there is a specific toggle called "Passcode Changes." If that's set to "Don't Allow," you're stuck until you toggle it back.
Hard Truths About Security
Let's be real for a second. If you use the same passcode for your iPhone that you use for your ATM card, you're making a mistake. If you use the same code as your iPad, you're doubling the risk.
Security experts from firms like CrowdStrike or Mandiant often emphasize that "convenience is the enemy of security." We love Face ID because it’s invisible. But the passcode is the foundation. If that foundation is weak, the whole house is vulnerable.
Switching your code every six months might seem like overkill, but in an age where data breaches are literally a daily occurrence, it’s a small price to pay for peace of mind.
Actionable Next Steps
Don't just read this and close the tab. Do the work.
- Audit your current code. Is it a date? Is it part of your phone number? If yes, change it right now.
- Enable Stolen Device Protection. It is located right under the passcode settings. Toggle it to "Always" instead of just "Away from Familiar Locations" if you want maximum security.
- Opt for 6 digits minimum. If you’re still on a 4-digit pin, you’re living in 2014. Move to 6 digits or a custom alphanumeric string.
- Clean your screen. This sounds silly, but oil smudges on your screen can actually show which numbers you press most often. A thief doesn't need to see you type; they just need to see the fingerprints.
- Check your Apple ID recovery. While you're messing with security, ensure you have a "Recovery Contact" set up. This is a trusted friend who can help you get back into your account if you're ever completely locked out.
Changing your iPhone passcode is a five-minute task that prevents a five-month nightmare of identity theft. Take the five minutes. It's worth it.
