OSH

OSH turns your iPhone into a hardware-backed approver for zero-trust SSH access. Instead of long-lived SSH keys scattered across laptops, your team's gateway issues short-lived SSH certificates only after a human approves each request. OSH is where that approval happens — on a device you carry, protected by Face ID and the Secure Enclave. HOW IT WORKS • Enroll your device by scanning the gateway's QR code. • When someone requests SSH access, OSH shows you who, what, and where. • Approve or deny with Face ID. Your approval is signed by a key that lives only in the Secure Enclave. • The gateway issues a short-lived certificate — no standing keys, no shared secrets. WHY IT'S SECURE • The signing key is generated inside the Secure Enclave and is non-exportable — it can never leave your iPhone. • Every approval requires biometric authentication. • OSH connects only to the gateway you configure. It has no analytics, no trackers, no ads, and no third-party SDKs. FOR TEAMS • Role-aware: signers, admins, and root see the controls appropriate to them. • Review access rules, approval history, and gateway logs from the app. OSH requires a compatible zero-trust SSH gateway to connect to.
