@gorgiselkov I believe that one might not be working because it's a skeleton plugin, and not an actual SSO auth (as stated on github page), unless you've configured it yourself but, it doesn't seem like it.
just installed dev version 0.7, in console log that buildin plugins can cause err -)
installed sso steam in 0.7, plugin unstable, sometime working, sometime not working
is there compabality list for plugins? or compabality tests for plugins?
