Score: 7.0/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 6)

Syn is a security tool that lets you approve remote sudo requests on Ubuntu machines from your Mac using Touch ID. It intercepts sudo invocations via a PAM module, sends signed approval requests over a mutually authenticated TLS connection, and requires fresh biometric authentication for each request. The project is interesting for its end-to-end security design, including secure enclave key storage, release binding, and robust recovery mechanisms.

Target audience: devops, system administrators, security engineers
