If you haven't already set up your connection to chat.remark.as, use this command:

/server add remark chat.remark.as/6697 -ssl

If you have already set up a connection to chat.remark.as, or if that command fails with a message like irc: server "remark" already exists, can't add it!, then use these commands to ensure that SSL/TLS is enabled for your connection:

/set irc.server.remark.addresses "chat.remark.as/6697"
/set irc.server.remark.ssl on

Now, configure SASL with the credentials found on this page (when authenticated:)

/set irc.server.remark.sasl_mechanism PLAIN
/set irc.server.remark.sasl_username <nickname>
/set irc.server.remark.sasl_password <password>
/save
