An authentication system which uses an authentication priority list based on dynamic and virtual grouping of terminals used for authentication, resulting in an efficiency improvement of authentication priority sequence in 1:N type authentication, and hybrid authentication by switching authentication logic between 1:1 and 1:N authentication. Masking of pre-logged-in users for the authentication priority list in 1:N authentication improves the efficiency of the authentication priority sequence in 1:N type authentication.
