Dynamic Password is the extension to provide better security to WordPress.
This plugin helps to change the user password every minute, every hour, every day, every weekday, every month or every year dynamically, without doing any extra work.
When you go to user profile page, there you can see “Set Dynamic Password” field below Users > Account Management field, where you can put any text, characters or dynamic strings that you can select from below dropdown. 
Also, you can see your current dynamic password preview that must be matched during login.

This plugin lets you specify a header image for each post, page, custom post type or archive page individually, from your default headers and custom headers.
It adds a meta box in the post edit screens with the header selection and a settings field in the edit profile and each taxonomy edit screen. 
If no specific header is specified for a post it will fall back to the default selection. 
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.
Thanks to Erik T. for the idea to this plugin!
