Globally set a password for all password protected posts and pages.
No. It allows you to use a global password for every post that you choose to password protect.
Despite the name of the plugin, anything that is password protected on your blog will use the global password - this includes posts, pages and custom post types.
Visit the 'Settings -> Global Post Password' menu in WordPress.
Yes. Only users with the 'manage_options' capability can change the global post password. By default, only administrators have this capability.
Visit the 'Settings -> Global Post Password' menu in WordPress and the password will be displayed there. And don't forget it again.
If you want to remove the global post password functionality and return to per-post passwords, just disable or uninstall the plugin and normal password protection will return. Password protected posts will remain protected with the password you last set under 'Settings -> Global Post Password'.
This plugin uses WordPress' built-in password protection system and simply enables you to set the password for all password protected posts globally. There are no known ways to read a password protected post without knowing the password for it.
Yes. Try my Logout of Password Protected Posts plugin which provides this functionality.
