Is it possible to change the passphrase for storage? I understand this is probably not trivial, but hoping there might be some way
You can run the CLI version with the password command to change the storage passphrase. It is actually trivial, since the passphrase is used to encrypt/decrypt the config file and all this command does is to decrypt the config file using the old passphrase and then encrypt it using a new one.
That worked, thanks!
