This plugin adds registration date and last login date columns on the “Users” page. 
It also checks whether user logs in within 30 days after the registration if he does not his account is deleted – this option is disabled by default, you can change this settings on Check Last Login Settings page in Settings menu.
WARNING! The plugin is not updating the login time when logging through stored login cookies.
I am open to suggestions to improve the plugin !

Check Last Login

Simple plugin which checks user's login status and displays registration date and last login date columns on the "Users" page.

This plugin redirects newly-registered users to the Admin -> Edit Profile page when they first log in. Until they have changed their password, they will not be able to access either the front-end or other admin pages. An admin notice is also displayed informing them that they must change their password.
New administrators must also change their password, but as a safety measure they can also access the Admin -> Plugins page.
