No. Not even during the initial setup or backup. The onboard microcontroller generates a wallet using a high-quality hardware random number generator to create entropy. The onboard slot for a micro SD card allows offline backup and recovery. There is no need to expose your wallet while typing on a keyboard or displaying recovery information on a screen, leaving it susceptible to theft by key logging, screen captures, and cameras.

Unlike other hardware wallets, you can backup your wallet at anytime and as often as you like. Switch between different wallets in a snap.

We appreciate paranoia. Therefore, additional entropy is added to the two hardware random number generators in three ways. First, in order to remove the need to trust the hardware, we add entropy through random bytes set during the factory installation. Second, in order to remove the need to trust us, the firmware derives entropy from your device password. Third, the BitBoxApp also generates entropy and passes this into the BitBox02 when you create a wallet.
