Hi @stefanozinnanti, thanks for your question.
Wordfence doesn’t offer an option to hide wp-admin or wp-login.php. With certain “security through obscurity” methods, this would only serve to slightly slow down somebody with malicious intent rather than stop them.
Our thoughts on altering the wp-login URL is discussed in this video which is provided for your information: https://www.wordfence.com/blog/2017/10/should-you-hide-wordpress-login-page/
Using strong account passwords and two-factor authentication, along with keeping your WordPress and plugin versions up-to-date should offer the best level of security.
Thanks,
Peter.
