with access adress like: login: firstname.lastname@example.org
I believe COPS is entirely separate from running a Calibre Server. I think the only thing it's using is your giant database file, which has no security.
I don't believe that COPS has any user management, but I could be wrong. I don't really care who "accidentally" has access to my library so it's not a feature I would use.
You could simulate this feature by using an ".htaccess" file. It sounds scary, but it really is not. Do a Google search for password protecting a directory with ".htaccess". I would put that file in your root directory and then anytime someone goes to your COPS Library they would get a popup asking them to login.
