Forgot the passcode on your new iPhone 18 Pro or iPhone 18 Pro Max? You are not alone. Face ID makes it easy to forget the digits behind it, until a restart, a software update or a few wrong guesses puts iPhone Unavailable on the screen and Face ID stops working.
The good news is that you can unlock an iPhone 18 Pro or Pro Max without the passcode. The honest news is that, apart from one short window, getting back in means erasing the phone first. This guide shows five working methods on iOS 27, from the one that keeps your data to the one that works even when the other four fail.
QUICK ANSWER
To unlock an iPhone 18 Pro or Pro Max without the passcode: (1) if you changed the passcode in the last 72 hours, tap Forgot Passcode? > Enter Previous Passcode; (2) otherwise tap Erase iPhone on the Lock Screen; (3) or erase it remotely with Find My; (4) or restore it in Recovery Mode from a computer; (5) or use a tool such as iSunshare iPhone Passcode Genius. Methods 2 to 5 erase the iPhone, so restore your backup afterward.
Before You Start: What to Know About the iPhone 18 Pro and Pro Max
1. Same steps for both models. The iPhone 18 Pro and iPhone 18 Pro Max run iOS 27, use Face ID and have no Home button, so every method below applies to both.
2. Almost every method erases the phone. iOS encrypts your data with your passcode, so there is no legitimate way to read it without that passcode. The only exception is the 72-hour previous-passcode reset in Method 1.
3. Back up first if you still can. If Face ID still opens the iPhone right now, go to Settings > [your name] > iCloud > iCloud Backup > Back Up Now before anything forces a passcode prompt.
4. Keep
your Apple Account password ready. Methods 2, 3 and 4 need it, and the iPhone
asks for it again at setup because of Activation Lock.
Method 1: Use Your Previous Passcode (Keeps Your Data)
If you changed your passcode within the last 72 hours, iOS 27 still accepts the old one for a short grace period. This is the only method that does not erase your iPhone 18 Pro or Pro Max.
Step 1: On the Lock Screen, enter any wrong passcode until iPhone Unavailable or Security Lockout appears.
Step 2: Tap Forgot Passcode? in the bottom corner.
Step 3: Tap Enter Previous Passcode. Type your old passcode. The iPhone unlocks immediately.
Step 4: Follow the prompts to create and confirm a new passcode.
Not seeing the option?
The previous-passcode option appears only if you changed the passcode in the last 72 hours. If you never changed it, or the window has
passed, move on to Method 2.
Method 2: Erase iPhone From the Lock Screen (No Computer Needed)
This is the fastest official route. It works when the iPhone is connected to Wi-Fi or cellular, is signed in to an Apple Account, and you know that account’s password.
DATA WARNING
This method erases all content and settings on the iPhone. Restore
from a backup after setup.
Step 1: Enter wrong passcodes on the Lock Screen until Security Lockout or iPhone Unavailable appears.
Step 2: Tap Erase iPhone. On some screens, tap Forgot Passcode? first and then Start iPhone Reset.
Step 3: Tap Erase iPhone again to confirm. Enter your Apple Account password to sign out of the account.
Step 4: Wait while the iPhone erases itself and restarts to the
Hello screen.
Set up the iPhone, create a new passcode and choose Restore
from iCloud Backup (or a computer backup) when asked.
Method 3: Erase Your iPhone Remotely with Find My
If you cannot reach the Erase iPhone option, or you are not near the phone, erase it from another device. Find My must have been turned on for the iPhone, which is the default when you sign in to an Apple Account.
Step 1: Get another i-Device, such as iPhone or iPad, open the
Find My app. Or visit icloud.com/find and log in your Apple account.
Step 2: Click All Devices and select your iPhone 18 Pro or Pro Max.
Step 3: Tap Erase
This Device and follow the prompts.
Step 4: When the iPhone restarts, set it up as new and restore your backup.
If the iPhone is offline
The erase command is queued and runs as soon as the iPhone
connects to Wi-Fi or cellular. Until then the Lock Screen stays as it is.
Method 4: Unlock iPhone 18 Pro in Recovery Mode
When the iPhone 18 Pro fails to connect the internet, you can resort to a computer, Windows PC with the Apple Devices/iTunes or Mac with Finder.
Step 1: Get your iPhone connected to the computer with the original USB cable.
Step 2: Quickly press and release Volume Up, then quickly press and release Volume Down. Then press and hold the Side button until the recovery screen (a cable pointing to a computer) appears.
Step 3: On the
computer, find your iPhone in Finder, Apple Devices or iTunes.
Step 4: When
asked, choose Restore (not Update). The computer downloads iOS 27 and
erases the iPhone.
Step 5: When the restore finishes, set up the iPhone and restore from a backup.
Watch the 15-minute limit
If the software download takes longer than 15 minutes, the iPhone
leaves Recovery Mode. Let the download finish, then repeat step 2 and choose
Restore again.
Method 5: Use iSunshare iPhone Passcode Genius
The official methods all depend on something: an Apple Account password, an internet connection, a working Erase option or a computer that recognizes the phone. If one of those is missing, a dedicated unlock tool is the practical fallback. iSunshare iPhone Passcode Genius is designed to unlock iPhone when you forgot the passcode, or Face ID/ Touch ID makes no sense on a disabled iPhone.
• You do not remember the Apple Account
password, so Methods 2 and 3 cannot finish.
• The iPhone is offline, or the Erase
iPhone option never appears.
• The screen is damaged and you cannot
comfortably use the Lock Screen buttons.
• You want one guided process instead of
managing Recovery Mode yourself.
How to unlock your iPhone 18 Pro or Pro Max with Passcode Genius
Step 1: Download and install iPhone Passcode Genius on your
computer from the official iSunshare website.
Step 2: Launch the program and choose the option—Unlock Lock
Screen.
Step 3: Hit the Start button. Then connect the iPhone with a USB
cable. If the program asks you to put the iPhone into Recovery or DFU mode,
follow the on-screen instructions. After that, click the Next button on the
software interface.
Step 4: Confirm the device information, then let the program
download the matching firmware package.
Step 5: Click Unlock to remove the passcode and wait until the
process finishes. Keep the cable connected the whole time.
Step 6: Set up the iPhone, create a new passcode and restore your
backup.
Activation Lock still applies
No unlock tool removes the Apple Account lock for you. After the
erase, sign in with the Apple Account that was on the iPhone. If you bought the
phone second-hand and it asks for another person’s account, ask the previous
owner to remove the iPhone from their account first.
What to do after you unlock your iPhone
•
Restore your backup. On the Apps & Data screen, choose Restore from iCloud Backup
or Restore from Mac or PC, and pick the most recent backup.
•
Choose a passcode you can recall. A longer numeric code or a custom
alphanumeric passcode is stronger, but only if you will remember it.
•
Store it safely. Keep the passcode in a password manager, not in the Notes app on
the same locked phone.
•
Use the passcode now and then. Face ID makes
it easier for people to forgot the screen passcode. Thus, you need to use it
from time to time.
FAQ: Unlocking an iPhone 18 Pro or Pro Max Without a Passcode
Q1: Can I unlock an iPhone 18 Pro or Pro Max without the passcode and keep my data?
Only in one situation: if you
changed the passcode within the last 72 hours, iOS 27 lets you sign in with the
previous passcode from the Forgot Passcode screen. After that window, every
method, official or third-party, erases the iPhone first. Restore from an
iCloud or computer backup afterward to get your data back.
Q2: Can I unlock my iPhone 18 Pro without a computer?
Yes. If the iPhone is online and
signed in to your Apple Account, you can erase it from the Lock Screen (Erase
iPhone), or erase it remotely from another device with Find My. Neither method
needs a computer.
Q3: Can Face ID unlock my iPhone 18 Pro when I’ve forgotten my
passcode?
Face ID will only unlock your device if iOS permits it. After a
reboot, multiple unsuccessful unlock tries, or an extended stretch without
unlocking the phone, iOS will demand your passcode — and Face ID cannot bypass
or reset it. If Face ID is still functional at this moment, back up your iPhone
right away before the system prompts you for the passcode.
Q4: What happens after so many incorrect passcode attempts?
iOS locks you out for longer and
longer periods and eventually shows Security Lockout or iPhone Unavailable. If
the Erase Data option is turned on in Settings, the iPhone can also erase
itself after ten failed attempts.
Conclusion
Forgetting the passcode on an iPhone 18 Pro or Pro Max is stressful, but it is fixable. If you updated your passcode within the past 72 hours, Method 1 lets you regain access without data loss. If not, Erase iPhone from the Lock Screen, Find My and Recovery Mode are the official routes, and each one needs a backup to bring your data back. When an Apple Account password, a connection or a working screen is missing, iSunshare iPhone Passcode Genius gives you a guided way to remove the passcode from your computer.
Whichever method you use, make a fresh backup once you are back in, and keep your new passcode somewhere safe.
