At my organization, we have a corporate-approved password manager, but shared folders are disabled. If someone needs a FID password, or something of the like, there are people that send the password in plain text over Slack, Teams, etc. and not everyone deletes their message containing the password afterwards.
You enter your secret on the website and it gets encrypted on the client-side before being sent to the database. A one-time-use URL is generated and then you send that URL to whomever needs the password. The backend never sees the secret in plain-text.
The tool is meant to be self-hosted - but I'm in the process of deploying it publicly for people to try out. I got the idea from my brother -- he was doing an internship at Tesla and said they had this being used internally, so I figured I would create my own as a little side project that I can then implement at work.
