Second Factor Authentication
Second Factor Authentication (2FA) can be activated to provide a second level of security:
transactions also need to be confirmed via your smartphone. This allows you to check the
amount, fee and recipient of each transaction through a secure channel to the device.
First, download and install the mobile app
on your smartphone from
digitalbitbox.com/start
(Apple iOS and Android are supported). For iOS, select the download from iTunes option.
Double click on the BitBox icon to start the app.
Do
NOT
press “Enable Full 2FA” before pairing your device with your smartphone via:
Options --> Connect Mobile App
You will be prompted to pair your smartphone with your BitBox. First, a QR code will appear.
Point the camera at the QR code and it will automatically be scanned. The pairing process
now begins. You will be prompted to enter in the number of times the LED on the BitBox
blinks. You may do this as many or as few times as you like, but it is recommended to do it at
least 5 times for high security. You may end the pairing process anytime after the first blinked
code by tapping on the BitBox LED between code blinks. Your smartphone will confirm if the
pairing is successful; you successfully entered the number of times the LED blinked. If you
made a mistake, you will be prompted to repeat the process.
Now you may enable 2FA:
Go to: Options --> Enable Full 2FA
Note that when you enable 2FA, creating new backups and mobile app pairing are disabled.
Additionally, Ether can be received but cannot be sent while 2FA is enabled.
To disable 2FA, the device needs to be reset, and your wallet must be restored from backup.
All your transactions will now require authentication and confirmation from your smartphone.
For example, when sending Bitcoin, complete details of the transaction are displayed i.e.
amount and send address, as well as fee, and other transaction data. Pressing “Accept”
continues the transaction signing process.
Restoring a wallet from backup
If you have lost, damaged or reset your wallet, you can restore it by following these
instructions.
1)
You have lost or damaged your wallet
: in this case you should order a new BitBox
and restore your wallet onto the new BitBox using the instructions below. Note that
due to the comprehensive security features of the BitBox, it is virtually impossible for
anyone to access your wallet should they find the lost BitBox.
Note: You could also restore your wallet to a software wallet (see instructions on
digitalbitbox.com/backup
). In this way you can be sure your wallet(s) are always
recoverable, independent of the BitBox.
2)
You have reset your wallet
(via Options-->Reset Device). In this case you can
restore your wallet using the instructions below.
