Get Fast Host servers have WordPress bruteforce protection, so you may see a POPUP Authorization box to provide "admin" as your username and password, so the real wp-login.php will be shown.
If this popup shows, just input admin as username and password. That's all
However, if you wish to remove this popup permanently, Just add the following lines of code in the ".htaccess" under public_html folder.
<FilesMatch "wp-login.php">
AuthType None
require all granted
</FilesMatch>
This will do the job! No more pop-up authorization box for wp-login.php access!
