How it works
Three steps. No setup wizard, no sign up, nothing to configure.
1Download
One file arrives. Windows may ask you to confirm placing the program on your computer; beyond that you are not asked anything.
2Open it
When the application opens, a nine digit access code and a single use PIN appear on screen. The code is grouped in threes, made to be read aloud on the phone.
3Read the code
Tell the code to your technician. When they try to connect, a permission dialog appears on your screen. Nothing starts until you allow it.
Behind the scenes
What a session actually does, in plain words.
What the code is for
The access code is not a password, it is an address: it tells the other side which computer to reach. On its own it cannot establish a connection; your approval is still required. A new one is generated every time you open the app.
Why there is a PIN
The PIN is single use and acts as a second threshold in case the code reaches the wrong person. It stops working when the session ends.
How the connection is made
Both sides connect outward and a server passes data between them. That is why there is no router setting, no port to open and no fixed address; it works the same in one office and across the country. On the same network the traffic goes directly and never touches the server.
Who holds control
A session carries at most two connections: one in control, one watching. Control can be handed over mid session and taken back. As long as you are the one sharing, the power to stop is always yours.
When the session ends
The moment the connection drops, so does the permission. Anyone who wants to reconnect has to ask again. What remains is the session itself: who connected, when, and for how long.
