A cluster automorphism is a $ \mathbb{Z} $-algebra automorphism of a cluster algebra $ \mathcal A $ satisfying that it sends a cluster to another and commutes with mutations. Chang and Schiffler conjectured that a cluster automorphism of $ \mathcal A $ is just a $ \mathbb{Z} $-algebra homomorphism of a cluster algebra sending a cluster to another. The aim of this article is to prove this conjecture.

Keywords: Cluster algebra, cluster automorphism.
