Your implementation of 'UserDetails' may hold any additional data. This is what gets stored in the SecurityContext which is later accessible after successful login.

You can later access it as (Assumes MyUserDetails implements UserDetails)

Object principal = SecurityContextHolder.getContext().getAuthentication();
if (principal instanceof MyUserDetails) {
  MyUserDetails mud = (MyUserDetails) principal;
  mud.getMyData(); //Extract your additional data here
}
