Built for Passport.
Passport Prime is Human Authority Hardware powered by KeyOS, Foundation’s Rust microkernel OS. It moves secure review and approval for high-stakes actions onto dedicated hardware, outside ordinary phones, laptops, browsers, and cloud accounts.
This is an early showcase of apps coming to Passport as we prepare the full SDK and app store.
The apps
Recovery
Social Recovery
Split a backup key across trusted guardians with Shamir’s Secret Sharing, then reconstruct a quorum to recover. No servers, no network.
Seed XOR
Splits one BIP39 seed into parts that are each an ordinary seed in their own right, and puts a set back together. Every part is required: N of N, with no threshold and no spare.
SeedQR Tool
Walks a SeedQR across the screen in small blocks so it can be punched or stamped onto metal without losing your place, then scans the copy you made and confirms it decodes back to the seed you started with.
Build your own for Passport Prime
Every app here is a KeyOS application (Rust plus Slint) talking to a host over WebUSB, QuantumLink Bluetooth, WebSocket, or animated QR. The same release-with-approval primitive is open to third-party developers.
