I need to do some user registration and login functionality for a website. I would like to use Supabase for this, but I'm not convinced this is completely secure. I need to be able to check if a user is logged in, and display certain content if this is the case. It seems to me this can easily be bypassed by disabling javascript on a page, since the check would be done in Javascript on the client-side. I hope I'm wrong, so I'm asking here.
