Is it necessary to use password in creating Bip32keystore ?

[DiwakarThapa]

In most of the code i have seen many people are creating keystone using password EthereumKeystoreV3(password: "PASSWORD"). Is it necessary ? if it is why ?

No, it is not necessary, if you go to the definition they have used bankexx as a password you can send an empty string to remove the password.
eg..
let keystore = try EthereumKeystoreV3(privateKey: dataKey)
