OSH
Read full descriptionHide full description
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 ā 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 ā no standing keys, no shared secrets. WHY IT'S SECURE ⢠The signing key is generated inside the Secure Enclave and is non-exportable ā 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.

Verdict
The clearest difference is update cadence: OSH at weekly against Domain Watcher's every 2 months. OSH also leads on iOS requirement (18.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
