How to Unlock iPhone Passcode with a Computer [2026]

Forgot your iPhone screen passcode and wondering how to unlock iPhone passcode with a computer? Whether your iPhone says iPhone Unavailable, shows Security Lockout, or you simply can't remember the passcode, you can use a Windows PC or Mac to erase the lock and regain access to the device.

Before using a computer, however, check whether Apple's Passcode Reset is available. If you changed your passcode within the last 72 hours and still remember the previous one, you may be able to unlock the iPhone with the old passcode without erasing it. Otherwise, resetting a forgotten iPhone passcode with a computer erases the data currently stored on the device.

Below, we'll walk through the current Windows and Mac methods, including Apple Devices, Finder, TunesKit iPhone Unlocker, iTunes, and Find My.

Before You Unlock iPhone Passcode with a Computer

There are a few important things to know before starting.

1. Try Your Previous Passcode First

If you recently changed your iPhone passcode and then forgot the new one, you might not need a computer at all. On iOS 17 and later, Apple provides a 72-hour Passcode Reset period during which you can use the previous passcode to regain access. After several incorrect attempts:

• Step 1. Tap Forgot Passcode? on the iPhone Unavailable screen.
• Step 2. Choose the Enter Previous Passcode option to enter your previous passcode.
• Step 3. Enter the old passcode.
• Step 4. Follow the onscreen instructions to create a new one.
• 

If the 72-hour period has expired or you don't remember your previous passcode, continue with one of the computer methods below.

2. Will Unlocking the iPhone Erase Data?

In most forgotten-screen-passcode situations, yes. Apple states that when you reset an iPhone after forgetting the passcode, the process erases the data currently stored on the device. Afterward, you can restore information from an existing iCloud or computer backup.

3. You May Still Need Your Apple Account Afterward

Removing the screen passcode doesn't necessarily remove account-based security protections. If Find My was enabled, you may need the Apple Account associated with the device when setting it up again. Therefore, make sure the iPhone belongs to you or you're authorized to manage it before proceeding.

Best Ways to Unlock iPhone Passcode with a Computer

Here's a quick comparison to help you choose the right method.

Method	Windows	Mac	USB Cable	Erases Current Data	Best For
Apple Devices	✓	—	Yes	Yes	Current Windows PCs
Finder	—	✓	Yes	Yes	Current Macs
TunesKit iPhone Unlocker	✓	✓	Yes	Yes for screen unlock	Guided passcode removal
iTunes	✓	Older macOS	Yes	Yes	Legacy environments
Find My	✓	✓	No	Yes	Remote erase

Apple currently directs Windows users to the Apple Devices app and Mac users to Finder when resetting a forgotten iPhone passcode with a computer.

Method 1. Unlock iPhone Passcode with Apple Devices on Windows

For a current Windows PC, Apple Devices should now be your primary official method, rather than iTunes. Apple's latest forgotten-passcode instructions tell Windows users to restore the locked iPhone through Apple Devices after putting it into Recovery Mode.

• Step 1. Power off your iPhone completely and then Connect your iPhone to a Windows PC.
• Step 2. Put the iPhone into Recovery Mode.
• Step 3. Launch Apple Devices on your Windows PC and select the iPhone from the sidebar.
• Step 4. Click Restore and follow the onscreen instructions. Apple Devices will download the required software and reset the locked iPhone.
• 

Method 2. Unlock iPhone Using Finder on Mac

If you're using a modern Mac, Finder is Apple's built-in way to restore a locked iPhone. The process is similar to Apple Devices on Windows: first place the iPhone into Recovery Mode, then use Finder to erase and restore it.

• Step 1. Connect your iPhone to your Mac using your USB or USB-C cable and put your device into Recovery Mode.
• Step 2. Open a Finder window. Look at the sidebar on the left; you should select your iPhone listed under "Locations."
• Step 3. You will see a prompt stating there is a problem with the iPhone. Click Restore.
• 
• Step 4. Finder will ask for confirmation to erase and restore the iPhone to factory settings. Click Restore. Keep your device connected until the process finishes.

Method 3. Unlock iPhone Passcode Using TunesKit iPhone Unlocker [For Mac & Windows]

Sometimes, the official methods above may fail due to unknown error codes (like Error 4013 or 3014), or you might find the complex button combinations difficult to time correctly. In these cases, using a dedicated third-party tool like TunesKit iPhone Unlocker can be a practical solution.

This software is designed to simplify the unlocking process by automating the firmware steps and bypassing common iTunes errors. While it is a paid tool, it offers a more guided interface for users who aren't tech-savvy.

Step 1. Connect iPhone to computer

Download and launch TunesKit iPhone Unlocker on your computer (Windows or Mac). Connect your disabled iPhone using a USB cable. From the main interface, select the "Unlock iOS Screen" option. Click "Start."

Step 2. Put iPhone into Recovery Mode/DFU Mode

Follow the on-screen instruction to put your iPhone into Recovery Mode or DFU Mode.

Step 3. Download fireware for your iPhone

Confirm your device information (Model and iOS version). Click "Download" to get the firmware package. This tool often downloads firmware faster and more reliably than iTunes servers.

Step 4. Unlock iPhone in one click

Once the download is complete, click "Unlock". The software will remove the screen lock. As with official methods, this will still erase your data to ensure security.

Method 4. Unlock iPhone via iTunes [For Older Windows Users]

iTunes is no longer the primary choice for current Windows PCs, but it hasn't disappeared completely. Apple still documents iTunes for Windows PCs that don't use the Apple Devices app and for macOS Mojave or earlier. Therefore, this method is most useful for older environments.

• Step 1. Open iTunes on your computer. Ensure the software is updated to the latest version to avoid connection errors.
• Step 2. Plug your charging cable into the computer, but do not plug it into the iPhone just yet.
• Step 3. Put your iPhone into Recovery Mode while connecting the cable to your iPhone.
• Step 4. Your computer software will detect a device in trouble. A pop-up window will appear. Click Restore. Do not choose "Update," as this often fails when the device is disabled.

Method 5. Erase a Locked iPhone from a Computer with Find My

What if you want to unlock the iPhone from your computer but can't connect it by cable? You may be able to use Find My through a web browser instead. This isn't a traditional USB computer-unlock method. Your computer simply acts as the browser used to send a remote erase command to the locked iPhone.

Apple recommends this as an alternative when you can't reset the iPhone with a computer using the recovery process.

• Step 1. Open any web browser on your computer and navigate to the iCloud website.
• Step 2. Sign in with your Apple Account credentials.
• Step 3. Click on All Devices at the top of the map interface and select the locked iPhone from the dropdown list.
• Step 4. Select Erase This iPhone. Confirm the action by entering your Apple Account password again. The iPhone will receive the signal remotely and begin the factory reset process immediately.

Can You Unlock iPhone Passcode with a Computer Without Losing Data?

Normally, no. If you've completely forgotten the iPhone screen passcode and need to reset it with Apple Devices, Finder, iTunes, or a screen-lock removal tool, the device must be erased. Apple explicitly states that resetting an iPhone after a forgotten passcode erases the data currently on it.

There is one important exception:

If you changed your passcode within the last 72 hours, use Apple's Passcode Reset feature and enter your previous passcode. This can let you regain access without resetting the device.

If that option isn't available, your best protection against data loss is an existing backup.

After the Unlock: How to Restore Your Data

Once the "Hello" screen appears, your iPhone is technically a new device. However, you can bring your digital life back during the setup process. Follow the on-screen setup instructions until you reach the "Transfer Your Apps & Data" screen. Here, you will have the option to:

• Restore from iCloud Backup: Use this if your phone backs up automatically over Wi-Fi.
• Restore from Mac or PC: Use this if you manually back up your phone to your computer.
