You may wish to change your Apple ID log/pass with a complex password you don’t use for anywhere else.
If you share the same or similar log/pass combo with another service (e.g. Yahoo, Twitter, Facebook, etc.) and that service is compromised then anyone with that information simply needs to try the same combo elsewhere
