Before you start the set-up process make sure that you have decided what you salt & phrase is going to be. The salt & phrase is the most important part of the Bitfi wallet infrastructure and is the wallet itself. Please read the Quick Start Guide that comes with the device to choose a proper phrase. Your device will use this as the input to calculate private keys as the output for whatever assets or features you are using.
Do not worry if you choose a salt & phrase that is not ideal; you can use it for practice and to get familiar with the operation of the Bitfi wallet infrastructure. You can create an unlimited number of wallets with the Bitfi device and you can always create a new salt & phrase.
