Verified steps Enable RLS on every exposed table: ALTER TABLE x ENABLE ROW LEVEL SECURITY Write policies per operation (SELECT/INSERT/UPDATE/DELETE) using auth.uid() Client code uses the anon key + user JWT (policies enforced) Server-only code may use the service_role key (BYPASSES RLS — never ship it client-side) Known gotchas A table without RLS enabled is fully readable/writable to anyone with the anon key — the #1 Supabase security hole service_role key bypasses ALL policies; leaking it = full DB access Policies don't apply to views by default (security_invoker=on needed, Postgres 15+)
