Signal

About

Signal is end-to-end encrypted open-source messaging software available for Android, iOS, Linux, MacOS, and Windows. It is tied to (and identifies, when connected to other users) the phone number of each user; it's not clear why this is so.

How to

• Installation:
  • /mobile/Android
  • /desktop/Linux
• Setup (post-installation)
  • /contacts
  • To be documented:
    • device fingerprints and all that kind of stuff that I don't really understand.
