It looks like the only options are local-only (single device) or cloud-synced (bulwark cloud). I want credentials that are not tied to a single device OR tied to a cloud service. I want to be able to make backups to be used in the case of device failure or loss, and I don't want to be tied to some "underlying cloud account" (in Yubico's words). Just standalone, backupable credentials. Can you do that?
