A knowledge base article about I use Citrix to access my applications. Do I have to do 2-Step every time I log in? provided by the UC Berkeley IT Service Hub - Knowledge Portal
We are currently exempting the Citrix browsers from 2-Step verification until we are ready to require 2-Step for the Citrix login level. Our goal is to only require 2-Step verification when you log into Citrix so that you don't have to do this for the browsers within the Citrix environment. This will go in effect as of April 16, 2018.
