[wp-hackers] Admin Login Brute Force Attacks (Revisited)

[Andrew Ozz]

Another good prevention measure is to set a simple htaccess password (or 
equivalent) only for wp-login.php. Yeah, the users will have to enter 
two passwords when logging in (heh, pseudo 2-step authorization?), but 
the bots only hit Apache not getting to PHP at all. Works on most shared 
hosting and reduces server load.

AuthType Basic
AuthName "[whatever]"
AuthUserFile "/path/to/.htpwd"
<Files "wp-login.php">
require valid-user
</Files>
