Needs offline mode for friends

Im only interested in using the mobile app for 2 factor authentication. I want to be able to use it for that without appearing online to friends.

When I select "go offline" I still see my friends statuses, so I assume Im still online there too.

Ill skip 2 factor and uninstall the app until this is implemented.
