+Get a personal access token - in RocketChat web interface go to
+

+
+eg. https://open.rocket.chat/account/tokens

 Then connect with IRC client, for example:
 
-    irssi  -c localhost -p <irc_port> -w <RocketChat secret token>
+    irssi  -c localhost -p <irc_port> -w <RocketChat personal access token>
 
+The user id generated together with the access token is not required.
 
+Note: ircrc uses the PASS command which is part of the original irc protocol and rarely used today - as opposed to the modern SASL authentication which also has a usename.
