I am responsible for the security of a company where passwords are currently stored locally with a password manager, but if another employee needs a password, they are shared via cloud based programs like Slack or Teams, which I want to prevent.
My idea was a local server that removes messages once they have been read or stored for more than 1 minute. (I don't want a network-based password storage, just a way to securely share passwords over the network.)
Does anyone have recommendations/experience with such software or is the idea generally stupid?
