Trying to hide my id from source code

Hello,
My goal with your plugin is to hide my id that i am using to connect to my wordpress ; i don’t want that everybody can find my id on my source code and try to break in. I guess that if you have my url login and my id you just need to try several password to connect. That is not good.

I desactivated the option author page but it is still visible on my source code. It is normal ? And if i click i get a 404 error because the page is not here anymore but you can still guess my id very easily with this informations on my source code. Is it normal or is it my theme ? You can see an example of the admin id here :

My theme is valenti

Thanks a lot,
