Linked devices

Device linking gives a new device its own credential and lane. The existing device approves the relationship; it does not transfer its credential.

Flow

The new device starts a short-lived linking session and displays a QR code. The existing device scans the code, shows the exact wallet and device request, and approves it with fresh authentication. Both devices then observe the final result.

Expire abandoned sessions, stop polling when the UI unmounts, and make repeat scans idempotent. Display the device name and creation time after success so the user can recognize and revoke it later.

Use the React useDeviceLinking, useQRCamera, QRCodeScanner, and ShowQRCode surfaces where they fit. Handle every LinkDeviceResult branch.

See linked devices for protocol and revocation detail.
