title: Where to put "FASTLANE_SESSION" value?
body: <p>I'm using <strong>fastlane</strong> with <strong>Fastfile</strong> and <strong>Appfile</strong></p>
  <p>According <a href="https://github.com/fastlane/fastlane/tree/master/spaceship#2-step-verification" rel="nofollow noreferrer">this</a> doc, i did create <em>FASTLANE_SESSION</em> variable in order to not enter a two-factor verification password every buildtime. But can't figure out where and how to put it to make it work. I don't use CI service, only fastlane in command line to deploy my ios build. Help please.</p>
