What is Signal Desktop?
Signal Desktop is an app that lets you send or receive Signal messages using your laptop or desktop computer. All messaging is private and syncs with Signal on your mobile phone.
Why use it?
You can comfortably chat using your full desktop or laptop keyboard. If you start a conversation on the Desktop and need to move around, just pick up your phone and continue messaging from there.
What do I need?
Can I install Signal Desktop without a mobile device?
No. Signal Desktop must link with either Signal Android or Signal iOS to be available for messaging. See point 1 in the 'What do I need?' section above.
