E-mails the site owner if anyone reaches or attempts to login to the site. Also shows the user names they attempt to login with.
This is a Security focused plug-in, which will send an email to the Administrator of the WordPress site each time login page is reached.
If someone attempts to login, it will also send the user name they tried logging in with, as well as their IP address, User-Agent, Timestamp, and the Referral URL.
If you see multiple attempts to login at times you are not logged on to the site, this means someone is attempting to brute force their way into your site, and you should ban the offending IP address from your site. Especially if they are trying multiple names, or sending them rapidly, one after another.
