Use Signal Private Messenger over the Tor network with Whonix.

Anonymity Specific

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 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.

It is possible to install the standalone Signal Desktop application version for Linux in Whonix-Workstation^™, and tunneling the application over the Tor network. However, this configuration is not recommended because although the traffic will be routed over the Tor network, Signal requires the user provide a phone number for verification. See Phone Number Validation vs User Privacy.
