I've been using 1Password non-subscription version (6) for years and am looking to switch over to the subscription version. My wife and I have been using a single password database for years, and it's not clear to me what the Families subscription gets me (for another $24/year) that I need. Does the subscription version not allow multiple people (devices) to log into a single multi-vault database, or can we just keep doing what we're doing now with a single subscription?
