With this package you can add different passwords to different pages of your site. This may be useful if you want to enable a "client page" without clients registration.
You can easily modify the "password request" page by overwriting the single page (copy /packages/page_password/single_pages/passwordrequest.php to /single_pages/passwordrequest.php).
NOTICE: due to this c5 behaviour , in 5.6.x full page caching must be disabled to let Page Password work correctly. (Thanks kevinmcd)
