How to wipe a phone or laptop before selling it

Teach: How to wipe a phone or laptop before selling it

What to say

Before you sell, trade in or recycle a phone or laptop, back it up, sign out of your accounts and turn off the device's lost-device lock or activation lock, then run the built-in reset that erases all content and settings. Remove any SIM or memory card. Only a factory reset protects you; deleting files by hand leaves them recoverable, and a locked device is useless to the next owner.

What to show, in order

1. Back up the device and check the backup finished.
2. Sign out of your main account, which also turns off the lost-device lock or activation lock on most devices.
3. Unpair watches, earbuds and other accessories.
4. Sign out of messaging, banking and password manager apps.
5. Run the built-in erase all content and settings or reset option from the system settings.
6. Remove the SIM card and any memory card.
7. Remove the device from your account's list of trusted devices online.
