BC Vault is the most secure device for your crypto assets because it randomly generates independent wallets that are not linked to the same BIP39/44 recovery seed. Each wallet can be locked with up to 4 codes (Global password + PIN, wallet password + PIN), and backed up individually with all passwords on a microSD card or on paper. Ledger, Trezor and Keepkey wallets can be restored only with the given seed phrase, which is not encrypted, so it has to be kept somewhere safe.
