This is a bit different. It's not a password manager app, it's more a standard for storing passwords encrypted with GPG in ~/.password-store and a reference CLI implementation. Several GUI clients exist to interact with the passwords, as well as tools to import from other password managers etc.

It sounds like a good idea, but I'm worried that a client could be at risk of a software supply chain attack - I don't think I will have the expertise to evaluate each new version.
