I was looking around WordPress.org at idea’s, that the community was suggesting. I took the Password Suggestion idea and made a small change to 2 of the core scripts. This change will give the administrator of a blog the ability to randomly generate password for users they are adding or editing. This was a 5 min project and you can see the changes below. I have also made it possible to see plain text passwords in the password fields. I don’t know if I am suppose to release stuff like this for WordPress and I hope I have not offended anyone on the core development team.

Installation is pretty easy

But first I can not stress this enough as you will be changing core scripts. I am not responsible if it breaks your site.
BACKUP BACKUP BACKUP

Install by downloading the files

1. Download the fies here.
2. Backup user-new.php and user-edit.php located in /wp-admin.
3. Extract file in /wp-admin directory via ftp or scp.

Install by changing the files

 Open /wp-admin/user-new.php in your favorite editor (I use VIM)
