Configuring SASL for WeeChat

Here’s a simple guide for password-based authentication, based on the WeeChat quick-start guide.

If you haven’t already set up your connection to Libera.Chat, use this command:

/server add libera -ssl

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

/set irc.server.libera.addresses ""
/set irc.server.libera.ssl on

Now, configure SASL:

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

It is recommended to store the password as secured data (skip setting passphrase if already set):

/secure passphrase <passphrase>
/secure set libera_password <password>
/set irc.server.libera.sasl_password "${}"

For more complete instructions, including non-password-based mechanisms, see the official WeeChat documentation.
