Resetting an iPhone without an Apple ID password can be challenging, but it’s possible with certain steps. First, try using the iForgot tool at iforgot.apple.com website to recover your Apple ID or reset the password. If that doesn’t work, you can put your iPhone into recovery mode and restore it via iTunes or Finder. However, keep in mind that activation lock will still require the Apple ID credentials after the reset. If you’re the rightful owner and face issues, contacting Apple Support with proof of purchase can help unlock your device. Always safeguard your Apple ID credentials for future use.
