I built a tool to scratch a ux itch we have at my team - we often need to send secrets, env files for tests setups, tokens, so on between computers. The usual flow for this is to create a temporary secret in 1pass, give access to the teammate and send the link over slack. Stringphone lives in the CLI and adopts CLI semantics - it allows to effortlessly cat your secrets on to your teammates machine - kind of a mailbox/clipboard experience. Messages are e2e encrypted and sent over a relay server in a way that the server cannot deduce who is messaging who.
