Custom Global landing page, User object

I am trying to build a custom landing page where I would like to show a set of projects before login and then show another set of projects post login.

I was hoping I can access allowedProjects from the User object, but thats not accessible. All I can get is {{user.name}} and no other user fields are visible on custom global landing page.

Can you please help me understand why? is there some other setting I need to do?
