The paper studies cyclic vectors for composition operators on the classical Hardy space induced by disk automorphisms. In particular, the paper contains results about when a Blaschke product is such a cyclic vector. As a byproduct, the paper obtains a new characterization for Blaschke products that are not finite products of interpolating Blaschke products.
