Each Satochip hardware wallet is delivered non-initialized to the customer.
During the wallet initialization with the suitable Satochip client, the seedphrase is shown on the screen and must be confirmed by the user.

THIS IS THE ONLY TIME the seedphrase is visible to the user and the only opportunity to do a backup of it!

After that, it is no more possible to export the seedphrase or any private key from the device.
The seedphrase and optionally the PIN code are the information the user needs to recover the Satochip hardware wallet on another hardware wallet.
