When the plugin is turned on, the password protected pages will be hidden. The user who knows the access URL continues to be able to access to the pages.
Optional settings: The unlocked password protected page will be locked again after the idle time (Value of Idle time for Password Protected Pages).

WP Hidden Password Protected Pages

I just installed this it works great.
My only criticism is that you fail to explain how to make the page password protected and that had my flumuxed for a while.
To anyone reading this, you change the page visibility to password protected when editing the page.



Works Great!
