Life of a Plesk Admin

If you are creating a new passwd file:

 C:\wamp\bin\apache\Apache2.2.11\bin\htpasswd.exe -c passfile username

If your are editing and existing password file:

 C:\wamp\bin\apache\Apache2.2.11\bin\htpasswd.exe passfile username

.htaccess contents:

AuthType Basic
require valid-user
Satisfy all
AuthUserFile C:/webroot/passwdfile
AuthName "My Secret Folder"

Move the created pass file to the desired location. and add a .htaccess file to the folder you want to protect and then gracefully restart apache.

This is done through the wamp system tray icon.
