Secretive is a macOS app that stores and manages SSH keys using the Secure Enclave, making them unexportable and requiring Touch ID or Apple Watch authentication for access. It addresses a critical security gap by preventing key theft and providing notifications on key usage, with an auditable build process and smart card support for older Macs.

Target audience: backend devs, devops, security engineers
