The phrase hardware wallet might make it seem like your bitcoin live inside the wallet itself, but that's not the case-bitcoin is never in your device at all...Instead of storing your bitcoin, your hardware wallet protects and stores the keys used to unlock-or spend-bitcoin from those addresses.
When you set up a bitcoin hardware wallet that respects best current practices, you should be prompted to back up your wallet using 12 or 24 words...Your seed phrase is like the 'key to the castle,' it contains everything you need to recover and use a key to all of the addresses protected by the seed phrase.
