Do I need separate accounts for Lovable and Supabase?

Yes, you need both a Lovable account and a Supabase account. However, the integration is seamless—after connecting, Lovable can create Supabase projects or connect to existing ones. You don't need to manage Supabase separately for basic use cases. For advanced settings (RLS policies, Edge Functions, secrets), you can dive into Supabase's dashboard, but Lovable scaffolds most things automatically.
