Do you think the WordPress administrator login is secure enough? As a system administrator, I have received lots of report that hackers(bad user) always logged into their WordPress administrator page and modified their themes and make the WordPress page an under attack pages.
How could them make this done? With a Wi-Fi connection from HotSpot, PC that affected by Viruses, Trojan, etc. They could easily caused this problem.
However you can get the Secure Sockey Layer (SSL) Certificate to encrypted your administrator login. To get this done, you may buy SSL certificate from your hosting provider and force your WordPress back-end with SSL(https) page.
To get this done, open the wp-config.php from your WordPress file and enter the command below from last line.(actually any line will do)
define(‘FORCE_SSL_ADMIN’, true);
