Protect user login page with Basic Auth
From your question


  Is there another ways to make the login more safe?


Yes,try one of the following modules

Login Security


  Login Security module improves the security options in the login operation of a Drupal site. By default, Drupal introduces only basic access control denying IP access to the full content of the site.


Secure Login


  Secure Login module enables the user login and other forms to be submitted securely via HTTPS, thus preventing passwords and other private user data from being transmitted in clear text. Secure Login module locks down not just the user/login page but also any page containing the user login block (or other forms that you configure to be secured).
