We'll create fresh WordPress site with Password Protect All Posts installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin puts a global password selected by you on all posts. Based on Matt Mullenwegs plugin “Protect old posts”
I’ve looked for a plugin like this but couldn’t find one that fitted my needs so i this one. I hope it will be helpfull for someone else to.
BEWARE: This will write over all old passwords and replace it with the one you select.
