I store all my ssh keys as attachments. All my ssh keys are passphrase protected as well. When I do download the keys, it isn’t much of an everyday activity either I do not need to keep transferring ssh keys regularly to my Mac- it is either a one time or a set up related activity. 1Password is just fine for storing ssh keys as attachments. Have you considered writing to them to ask for what you need?
