In TorChat every user has a unique alphanumeric ID consisting of 16 characters. This ID will be randomly created by Tor when the client is started the first time, it is basically the .onion address of a hidden service. TorChat comes bundled with a copy of the Tor onion router readily configured so that it can be run as a portable application without any installation, configuration, or account creation.
