Configuring SASL for mIRC

mIRC added built-in SASL support in version 7.48, released April 2017. The below instructions were written for version 7.51, released September 2017. Earlier versions of mIRC have unofficial third-party support for SASL, which is not documented here. freenode strongly recommends using the latest available version of your IRC client so that you are up-to-date with security fixes.

In the File menu, click Select Server...
In the Connect -> Servers section of the mIRC Options window, select the correct server inside the Freenode folder, then click Edit
In the Login Method dropdown, select SASL (/CAP)
In the second Password box at the bottom of the window, enter your NickServ username, then a colon, then your NickServ password. For example, dax:hunter2
Click the OK button
