There are several methods to unlock an iPhone passcode without using a computer, especially if the iPhone is running iOS 15.2 or later:
- Use the "Erase iPhone" from the Security Lockout screen:
- After entering the wrong passcode multiple times, the iPhone will show an "iPhone Unavailable" screen.
- Tap "Erase iPhone" on the screen to begin erasing the device.
- You will need to enter your Apple ID and password to confirm.
- The device erases all content including the passcode, allowing you to set it up again.
- Use the Find My app on another iOS device:
- Open the Find My app on an iPhone or iPad where you are signed in with the same Apple ID.
- Select the locked iPhone from the device list.
- Choose "Erase This Device" to erase the locked iPhone remotely.
- Once erased, set up the iPhone anew or restore from backup.
- If recently changed passcode (iOS 17 or later):
- After wrong passcode attempts lead to Security Lockout, use the "Forgot Passcode?" option.
- Enter the previous passcode to reset to a new passcode without data loss.
Note: These methods require knowing your Apple ID credentials. All methods erase the device to remove the passcode unless using the recent passcode reset feature in iOS 17. If these options are not available, the official Apple suggestion is to visit an Apple Store or authorized service provider for help without a computer. These methods ensure you can unlock your iPhone passcode without a computer safely and legally.
