iPhone

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.

Live admin updates - Rules, Groups, Servers, Signers and Devices in the Admin tab now refresh by themselves. A change made by another admin shows up within about a second (with gateway 0.29.0 or newer; older gateways keep the previous 5-second refresh). Stronger approvals - When your gateway (0.29.0 or newer) sends the full details, the app now signs exactly what the certificate authority will issue. Older gateways keep working as before. Fixes - The last item you delete no longer lingers on screen. The "Offline" bar no longer appears by mistake before you finish registering. Added the Local Network permission description so gateways on a private network can be reached.
