Private Keys & Master Passwords
There are 4 keys associated with graphene blockchains:
Each key has different permissions associated with the blockchain (something we will touch upon in a later blog post). Your master password is a hash value of all 4 of those keys put together. This allows for easy restoration of an account and all associated keys with just one password.
Bravo does not store a copy of your private keys or master password on its servers to access the blockchain. Loss of this master password will result in failure to access your account, funds, rewards, tokens, and all associated account history on the blockchain.
