Step 1: Download, install and run the latest desktop app
Step 2: Plug in your Digital Bitbox, with a micro SD card inserted
Enter a wallet name and device password using the desktop app. The Digital 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 Digital Bitbox or to learn how to load your own wallet.
Use a mobile phone as a large screen for securely verifying transactions and receiving addresses created by the Digital 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 Digital 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 Digital Bitbox’s LED. All you need to do is count a few blinks and enter them in the mobile phone. See how below.
To begin, your mobile phone and computer need to be connected to the internet. First, connect the mobile app to the desktop app. Then, pair the mobile app with the Digital Bitbox as described below.
Step 2: Connect to the desktop app
Use the mobile app to scan the QR code presented by the desktop app.
Step 3: Securely pair the mobile app to the Digital Bitbox
Pairing only needs to be done once and can be redone at anytime.
Verifying addresses and transactions
Information received by the Digital Bitbox displays automatically in the mobile when connected to the internet. Otherwise, get the information by scanning QR codes presented by the desktop app.
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 Digital 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 Digital Bitbox.
