Setting up a hardware wallet, step by step
Before you plug it in
Check the box and the seal as lesson 2 describes. Then get the maker’s app, and nothing else.
Ledger’s is called Ledger Wallet (older pages still call it Ledger Live). Trezor’s is Trezor Suite.
Type the maker’s address into the browser by hand and follow its download link. The app is what checks the device is genuine, installs the coin apps and later updates the firmware, so a fake app defeats the whole exercise.
Set aside half an hour, alone, with a pen and the recovery card from the box. Put your phone face down. Nothing in the next half hour should be photographed, and nothing should be typed anywhere except the PIN and backup words on the device.
Here are each maker’s names for the same five things. A device from another maker follows the same steps under its own names, and its guide on the maker’s site gives them.
