Good approach @nihadness. But please have a look at the source of plone.app.layout.globals.portal.PortalState (here it is the @@plone_portal_state view) and search for anonymous. Then use that method with inverted logic.

However, we should delete this portlet in the future and setup a set of sane portlets during setup like here: https://github.com/senaite/senaite.lims/blob/master/src/senaite/lims/setuphandlers.py#L24

[nihadness]

Looks better now, I guess :)

You could even skip the python part in the condition and just write tal:condition="not:anonymous". But this is also fine;) well done
