Navigating your BitBox02 is made easy using 3 simple gestures. Use tap, slide and hold for password entry and navigating when making a transaction. The unique hold gesture ensures you won’t make any accidental transactions. For peace of mind, backups are made to a microSD card instantly and can be managed from the BitBoxApp.
Use the device in a way that suits you. USB-C plugs directly into your computer and comes with an optional USB-C to USB-A adaptor with cable included.
A secure chip is used for seed protection, brute-force prevention and device password hardening. Verify on the screen of the device what you are about to confirm, including all transaction details before signing.
Secure your favorite online accounts with universal 2 factor authentication. U2F gives you the ability to login to your online accounts securely using the BitBox02 as a physical security key. We focus our efforts on the top tier coins under active development. More coins are planned in the future.

Do my private keys ever touch my computer or the internet?
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.
What if a government or bully forces me to open my wallet?
Use plausible deniability. If you enable the optional passphrase feature, you will be prompted to enter a passphrase after entering the BitBox02 password. This option can be used to derive different wallets. Put some change in one to add plausibility.
Warning! Funds deposited to a wallet derived from a passphrase can only be recovered from the backup when enabling the passphrase option and entering the same passphrase text. This is an advanced feature.
