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:

1. Under Topics, tap Passwords & Security.
2. Tap Reset Apple ID password.
3. Tap Get Started, then tap “A different Apple ID”.
4. Enter the Apple ID that you need to reset the password for.
5. Tap Next, then follow the steps on your screen until you receive confirmation that your Apple ID password is changed.

Any information that you enter will not be stored on the device.

If your friend or family member’s device is using iOS 9 to iOS 12 and the Apple Support app can’t be downloaded, use the Find My iPhone app instead.

1. Open the Find My iPhone app.
2. When a Sign In screen appears, make sure the Apple ID field is empty. If you see someone else’s user name, erase it.
3. Tap Forgotten Apple ID or Password, then follow the onscreen steps.

Don’t see a Sign In screen? Tap Sign Out. After you sign out, make sure the Apple ID field is empty. Then tap Forgotten Apple ID or Password, and follow the onscreen steps.

In some cases, you may have the option to speed up the account recovery process or reset your password immediately by verifying a six-digit code that is sent to your primary email address. Find out more about account recovery.
