Check your device and get the official app
Unbox your Ledger and look for clear signs that it may have been tampered with. A new device should guide you through creating a PIN and generating a new recovery phrase; it should not arrive with a prewritten phrase or ask you to use one supplied by someone else. On your computer or phone, visit ledger.com/ledger-live directly and follow the download instructions for your operating system. Confirm that the app identifies your genuine Ledger device before continuing.
