Erase a device in Find My iPhone on iCloud.com
If your iPhone, iPad, iPod touch, Mac, or Apple Watch is lost or stolen, you can erase it using Find My iPhone if you set up Find My iPhone on the device before it was lost. If Find My iPhone isn’t set up on your missing device, see the Apple Support article If your iPhone, iPad, or iPod touch is lost or stolen. If you have Family Sharing set up, you can erase your family members’ devices, too. See the Apple Support article Family Sharing.
What happens when you erase a device in Find My iPhone?
A confirmation email is sent to your Apple ID email address.
After you erase a device, you can’t use Find My iPhone to locate the device or play a sound on it. However, you may still be able to locate your Mac or Apple Watch if it’s near a previously used Wi-Fi network.
Apple Pay is disabled for your device. Any credit or debit cards set up for Apple Pay, student ID cards, and Express Transit cards are removed from your device. Credit, debit, and student ID cards are removed even if your device is offline. Express Transit cards are removed the next time your device goes online. See the Apple Support article Manage the cards that you use with Apple Pay.
If you use two-factor authentication, the device that you erased is removed from your list of trusted devices.
If you erase but then find your device, you can restore the information on it with an existing backup. See the Apple Support articles Restore your iPhone, iPad, or iPod touch from a backup, Restore your Mac from a backup, and Restore Apple Watch from a backup.

Mac: Enter your Apple ID password or your family member’s Apple ID password.

Enter a passcode to lock the Mac (you need to use the passcode to unlock it).
For more information about trusted browsers, see the Apple Support article Two-factor authentication for Apple ID.
If the device is lost and you’re asked to enter a phone number or message, you may want to indicate that the device is lost or how to contact you. The number and message appear on the device’s Lock screen.
