How to Reset a Forgotten iPhone 15 Passcode

To reset an iPhone 15 when you are locked out, erase the iPhone with recovery mode or Find My, then create a new passcode during setup. Erasing removes the forgotten passcode, but it also deletes data that was not saved in a backup.

When do you need to reset an iPhone 15 passcode?

You may need to reset an iPhone 15 after forgetting the passcode, entering the wrong passcode too many times, or seeing “iPhone Unavailable” on the screen. The passcode cannot be recovered or displayed, so getting back into the iPhone normally requires erasing it.

Before erasing the phone, check whether the lock screen offers an Apple-provided option to erase or reset the device. The wording can vary with the installed software version. If no usable option appears, use recovery mode on a computer or erase the iPhone through Find My.

These instructions are for an iPhone you own or are authorized to manage. Erasing an iPhone does not remove Activation Lock, which is Apple’s ownership protection that requires the Apple ID previously associated with the device.

What do you need before resetting an iPhone 15?

Prepare the following before you reset an iPhone 15:

• A Mac or Windows computer and a compatible cable for the recovery-mode method.
• Another Apple device or access to iCloud.com for the Find My method.
• The Apple ID email address or phone number previously used on the locked iPhone.
• The Apple ID password, which may be required to erase, activate, or restore the iPhone.
• Enough time to erase the device, reinstall its software, and complete setup.

Anything stored only on the iPhone will be erased. Photos, messages, notes, app data, and other information can be recovered only if they were synchronized elsewhere or included in an iCloud or computer backup.

If you recently changed the iPhone passcode, the lock screen may offer a limited-time Apple feature that lets you use the previous passcode. Follow that prompt if it appears and you know the old passcode; otherwise, continue with an erase method.

How do you reset an iPhone 15 with recovery mode on a computer?

Recovery mode is a special startup screen that lets a computer erase an iPhone and reinstall its software. Use this method when Find My is unavailable or the locked iPhone cannot connect to the internet.

1. On a Mac, open Finder. On a Windows computer, open the current Apple device-management program available on that computer, or iTunes if that is what the computer uses. Update the program first if it cannot recognize the iPhone.
2. Disconnect the iPhone 15 from the computer. Turn off the iPhone by holding the side button and either volume button until the power slider appears, then drag the slider.
3. Connect the cable to the computer. Hold the iPhone’s side button while connecting the other end of the cable to the iPhone.
4. Keep holding the side button after the Apple logo appears. Release it only when the recovery-mode screen, showing a cable and computer, appears.
5. Select the iPhone in Finder or iTunes. When asked whether to update or restore it, choose Restore. Restoring erases the device and installs a fresh copy of the iPhone software.
6. Leave the iPhone connected while the computer downloads and installs the software. If the download takes long enough for the iPhone to leave recovery mode, let the download finish and then repeat the recovery-mode steps.
7. When the Hello screen appears, disconnect the iPhone and begin setup.

How do you reset an iPhone 15 remotely with Find My?

Find My can erase a locked iPhone 15 remotely if Find My was enabled on that iPhone before the lockout. The erase command requires the iPhone to connect to the internet; an offline iPhone will receive the command when it next comes online.

1. Open the Find My app on another Apple device, or open iCloud.com in a browser on a trusted device.
2. Sign in with the Apple ID associated with the locked iPhone 15. If using another person’s device, avoid saving your sign-in details.
3. Open the list of devices and select the locked iPhone 15. Confirm the device name carefully if several iPhones appear.
4. Select the option to erase the iPhone, then review and confirm the request. Enter the Apple ID password or complete identity verification if prompted.
5. Keep the iPhone powered on and connected to Wi-Fi or cellular service. The erase begins when the phone receives the command.
6. Wait for the Hello screen, then start the setup process.

If the iPhone does not appear in Find My, it may be associated with a different Apple ID or Find My may not have been enabled. In that case, use recovery mode on a computer.

How do you set a new iPhone 15 passcode after the reset?

After the iPhone 15 restarts at the Hello screen, follow the setup prompts. Connect to a network, sign in with the Apple ID that was previously used on the phone, and complete any requested account verification.

Choose an available backup when setup asks whether to restore data. An iCloud backup is restored over the internet, while a computer backup is restored by reconnecting the iPhone to the computer that holds it. If no backup exists, set up the iPhone as new.

Create a new passcode that you can remember but other people cannot easily guess. Store it in a secure password manager or another protected place. Do not reuse a code that someone else knows.

What should you do if the iPhone 15 is still locked?

If the iPhone remains on the unavailable or recovery screen, confirm that the erase completed and repeat the appropriate reset process. Try another compatible cable or computer port if the computer repeatedly loses its connection to the iPhone.

If setup requests an unfamiliar Apple ID, do not attempt to bypass Activation Lock. Check purchase records, family accounts, workplace management details, or the credentials originally used with the iPhone.

Contact official Apple Support if recovery mode repeatedly fails, the correct Apple ID is rejected, or you cannot complete account recovery. Apple may ask for the device serial number, account information, and valid proof that you own the iPhone. Support can explain the approved recovery options, but it cannot restore unsaved data erased during the reset.
