This plugin allows passwords for password-protected pages/posts to be passed directly through the URL.
The query string parameter that should contain the password is <code>pw</code>.
For example, if the URL of your post is <code>http://myblog.com/password-protected-page/</code> and the password is <code>PASSWORD</code>, 
then just append <code>?pw=PASSWORD</code> to it.
If the URL already contains a query string (for example, <code>http://myblog.com/?p=5</code>), then be sure to append <code>&pw=PASSWORD</code> instead.

Do you have a password protected post or page that has child (and grandchild) pages? Currently, you have to password protect each of these pages individually but, with this simple and efficient plugin, you can automatically password protect a page and all of it’s children automatically with the click of a button.
Once you choose the ‘Visibility’ option on a post and update it to ‘Password Protected’, you will be given a checkbox where you can opt into protecting all of that post’s children and grandchildren.
