So #Signal is supposed to be installed on a smartphone before you can use it on desktop? Unofficially, the desktop version is perfectly capable of creating new accounts. All you need is a number to receive an SMS or voice mail. Here is how.

Things got considerably worse in the past years. The process of setting up a standalone desktop version of #Signal got more complicated and is broken even in the development version where it is enabled. There is a pull request to fix this which itself became broken.
In the end I gave up and installed Signal in the Android emulator to create the account. Printed out the QR code so that I could show it to the webcam (orientation is important, just using a mirror didn’t work out).
Yes, Signal for desktop is still being neglected.
