What is Hardware wallet?
A dedicated device that holds keys and signs transactions after you confirm on it.
The point of the device is that the transaction you approve on its screen is the one that gets signed — a compromised computer cannot quietly change the destination.
Buy it from the manufacturer, never second-hand, and write the seed phrase somewhere physical rather than storing it as a photo.
