If they can't access any of their devices
You can reset your Apple ID password on a friend or family member's iPhone, iPad, or iPod touch using the Apple Support app or the Find My iPhone app.
Use the Apple Support app
To reset your password using the Apple Support app on a friend or family member's iPhone, iPad, or iPod touch with iOS 12 or later, the device owner will need to download the Apple Support app.
Ask the device owner to open the App Store on their iPhone, iPad, or iPod touch, then search for Apple Support and download the app. Then open the Apple Support app and follow these steps:
- Under Topics, tap Passwords & Security.
- Tap Reset Apple ID password.
- Tap Get Started, then tap "A different Apple ID."
- Enter the Apple ID that you need to reset the password for.
Tap Next, then follow the steps on your screen until you receive confirmation that your Apple ID password is changed.Â
If this doesn't help, you may need to contact Apple Support:
