If you publish many password protected posts (or even if you don’t), you may end up using the same password for each one. With this plugin you can define a global password from your ‘Settings -> Global Post Password’ menu, and switch password protection on or off from the writing screen with just one click. Whenever you change the global password, all password protected posts are automatically updated with the new password. Note that this plugin does not automatically enable password protection on every post. It allows you to use a global password for every post that you choose to password protect.
