Step 2: Plug in your BitBox, with a Micro SD card inserted.
Enter a wallet name and device password using the desktop app. The BitBox will create your first wallet and generate a backup on the micro SD card (SDHC cards are supported). Send coins to the wallet using addresses listed in the 'Receive' tab of the desktop app.
Step 3: Remember the password.
Remember the device password, and keep a copy of it somewhere safe.
Without it, you cannot access your wallet and cannot access the backup saved on the micro SD card.
Step 4: Remove the Micro SD card and store it somewhere safe.
The backup and device password can be used to recover your wallet. Check out the Backup Center to learn how a backup can be recovered without a BitBox or to learn how to load your own wallet.
Optional: Ethereum integration

That's it! You are ready to begin.
Use a mobile phone as a large screen for securely verifying transactions and receiving addresses created by the BitBox. This avoids man-in-the-middle attacks on computers that have been fully compromised (i.e. rooted). Optionally in addition, enable the mobile phone as a second-factor authentication (2FA) device using the desktop app's 'Options' tab.
Technically, a private and encrypted communication channel between the mobile phone and the BitBox is created using a hashed Elliptic Curve Diffie–Hellman (ECDH) key exchange in combination with off-channel information from a blink code, using the BitBox's LED. All you need to do is count a few blinks and enter them in the mobile phone. See how below.
Full second-factor authentication (2FA)
When full 2FA is enabled, possession of the mobile phone is required in order to spend coins. Full 2FA is enabled using the 'Settings' tab in the desktop app. Under the hood, an encrypted single-use PIN is sent to the mobile app, decrypted there, and returned to the BitBox when pressing the Accept button.
BE CAREFUL! Be sure to backup your wallet and pair the mobile app before enabling 2FA. Once enabled, the micro SD slot, necessary for backups, and mobile app pairing is disabled. These are re-enabled only after ERASING the BitBox.
