Start on the computer whose projects you want to access. In its Yuri Settings → Remote Instances, use Add a device in the connection section. This screen requires the host's client-management capability; it is not a VS Code setting.
Choose the reach before making the code
The pairing dialog offers local, LAN and Relay choices according to host availability. Local is for the same computer; LAN requires a reachable network address; Relay is for access beyond that network. Check the offered fallback option if you want both available routes.
Name the device and create the code. On a phone, scan it from the connection screen or paste the pairing link. In the desktop app, use Import link in Remote Instances. Redeeming the code creates the saved client connection; the code is single-use and expires.
Confirm the destination, not just the connection
Open a known project after connecting. A successful connection to the wrong host can look like missing sessions. The native phone app manages saved hosts under Settings → Switch instance; it does not expose the desktop's entire Remote Instances editor.
To remove access, revoke the client on the issuing host. Removing a saved connection locally and revoking its host credential are different actions.
A terminal-managed pairing
On the host, yuri connect-url --port 3000 --qr creates a direct-capable link for that instance. yuri connect-url --relay --qr instead creates a Relay-only link and requires a running, Relay-enabled host; it does not start one. Use the command's --help for address and binding options. Browsers can use the reachable web address and its login flow.
