Setup Signal Desktop
Signal actually has computer-based (Desktop/Laptop) client to interface or message easily without using your phone. This section guides you on how to setup desktop client and how to link it with your mobile phone.
Download Signal Desktop
The application for downloading the Desktop client is available at: https://signal.org/download/. Please download and then install it according to your operating system (e.g. Windows, Mac, and Linux).
Launch Signal Desktop
Once done, you may launch your Desktop Signal. This will produce a QR Code interface ready to link with your Signal Messenger on your mobile phone.
With both mobile and desktop ready for linking, you should now link them together.
Open Settings on Mobile
Head to your mobile's Signal Messenger and open the hamburger to the top right. Select Settings.
Set Linked Devices
Now select the Linked Devices option.
Add Link Device
Inside the list, you can select “+” button to add a link device.
Scan Link Device QR Code
A scanner will appear to scan the QR Code presented on Signal Desktop. You will need to grant camera permission in order to make things work.
Name Linked Signal Desktop
If everything is done correctly, your Signal Desktop will prompt you to name itself. You should name it in a way that you can recognize it via your mobile's Signal Messenger, not the other way round.
Sync and Ready to Use
Once done, your desktop Signal will sync with your phone's Signal Messenger for contacts and groups. Messages will not be sync for security reason as Signal Desktop is behaving as an independent terminal.
However, if both Signal Desktop and Signal Messenger are connected prior the arrival of the message, both Signal Desktop and Signal Messenger will receive a copy of it.
