and keystores can be stored online, such as cloud disk, or in their own U disk (hardware wallet takes advantage of this), which is relatively safer than online storage. Even if hackers steal your keystores, they can't steal the assets without the password of the keystores, so the password of the keystores is particularly important at this time

loss prevention

the main loss prevention strategy is multiple backup, multiple backup. For example, when backing up a wallet, not only the keystore, but also the mnemonic words and private key should be backed up. This is a multiple backup
