Quick start
First connection in six steps.
One account, a device at each end, and a request the host approves by name. Sharing a screen needs nothing installed; add the desktop app when the other person should also move the mouse and keyboard.
First connection
The host is involved from start to stop.
Owning the account starts nothing on its own. Every session waits on the machine being shared: it approves the request, chooses what to share, and grants any control.
Create the account
Enter your email and open the link it sends back. There is no password to choose. Add a passkey or TOTP later if you want the extra step.
Enroll both devices
Sign in on the computer you want to share and on the device you will watch from. Name each one so you recognize it in a request.
Install the desktop app on the host
Only needed if the other person should also move the mouse and keyboard. One download covers Windows, macOS, and Linux; sharing a screen needs nothing installed.
Approve the request
The host shows which device is asking and what it is asking for. Approve it and pick what to share. Nothing leaves the machine before that.
Connect direct-first
The two devices find a direct path when the networks allow one. When they do not, authenticated TURN carries the same encrypted packets.
Use as display, and stop when you are done
Any accepted viewer can switch to Use as display with Fit, Fill, 1:1, and rotation. Exit and Stop stay on screen the whole time.
Before accepting a request
- 01
Read the name
Confirm the device asking is one you expect to be asking.
- 02
Share the smallest thing that works
One window is usually enough. A whole screen shows everything on it.
- 03
Grant only what is needed
Leave it view-only unless the other person actually needs to click and type.
- 04
Know where Stop is
The tray icon and the session window both stop it, and Ctrl+Alt+Shift+F12 works from anywhere, including from inside a game.
- 05
Check the path
Direct is preferred. Authenticated TURN is a ciphertext-only fallback, not a general tunnel.
- 06
Stop and revoke
End the session locally, then revoke any device you no longer recognize.
Private by scope
Exact product sessions, never an account-wide VPN or proxy.
Signaling establishes the one authorized session and nothing more. Direct traffic is preferred; TURN relays encrypted WebRTC only when the networks leave no direct path. Neither creates a default route, a remote shell, or arbitrary network access.
