There are various services out there on the internet that provides a way to share secrets without the ceremony of creating user accounts (e.g https://onetimesecret.com). But i'm very hesitant to rely on random websites to share sensitive and confidential information.
Since I already put a lot of trust in 1Password and handling our most sensitive information, having such a service within 1Password for Business seems like a good fit for me.
I haven't put a ton of thought into this would work with your security model, but I would be interested in knowing if one time sharing of secrets was something you have considered?
