Hope the Slack team will properly implement SSO two-factor authentication policy - right now none of the Slack apps request re-authentication after thirty days once an account is signed into via SSO. Sign in once on OS X, Windows, iOS, Android and no further authentication needed. Looking at Google Apps SSO specifically but am assuming it affects other authentication providers. Might as well plug my tiny Slack auto-install/update script for the OS X app while I'm here - hope someone else finds it helpful: https://github.com/opragel/install_latest_slack_osx_app https://github.com/opragel/install_latest_slack_osx_app
