Idea for next Digital Editions updates

Hi, I work in the technical support service of an e-book store that uses Digital Editions.

What we see is that a considerable and constant number of users use the option "Authorize without an ID" and then, after deleting the authorization or reinstalling the software, they can not reopen their ebooks.

This option is very problematic, and I think it would be good if in the next updates it do not appear.

Thank you very much.
