Send Signal Messages over Tor with Whonix
Use Signal Private Messenger over the Tor network with Whonix.
The mandatory linkage of the desktop software application with a phone number makes it very likely adversaries can easily link any 'anonymous' use of Signal in Whonix with a user's real identity, even if a secondary phone number is used as a limited workaround. Notably, to date Signal has ignored user requests to enable registration with an email account as a possible alternative. For this reason alone, alternative options like Gajim and HexChat should be investigated instead; see Instant Messenger Chat for further information. Readers are of course free to ignore this advice -- see below for Whonix instructions.
- The number can be different form the device's SIM card; it can be a landline or VoIP number, so long as the user can receive the verification code and possesses a separate device to set up the software.
