Yes, Burner employs advanced security measures comparable to other leading hardware wallets. In fact, the unique non-extractable key approach and absence of seed phrases can offer an additional layer of security, potentially making it even safer by eliminating the risk associated with seed phrase management.

For storing large amounts of crypto assets, we always recommend using Burner in conjunction with a multisig account like Gnosis Safe and creating a backup Burner as no hardware is infallible or perfectly secure.
