Did you check 1Password developer tools, like SSH-agent server, git commit signing, and CLI? https://developer.1password.com/
Or the new item and file sharing. https://support.1password.com/share-items/
I put them under the same reliability umbrella (maybe even a touch higher) than Fastmail, which is high praise IMO.
Sorry, I don't mean to sound like an ass, they look like very well put together features. They just remind me of when Dropbox decided to start offering document editing. Not what I go there for.
We have a lot of 1Password customers with families and team members that require more than a single vault, need an option to recover team/family member access and often have to securely share data with other people, accountants and lawyers. Also, many of developers and admins that want to keep their SSH keys safe.
