This addon helps ensure user's security by alerting them when their user account is logged into.
At this time there is nothing to configure, just install and it works.
When a user logs in, they will immediately recieve an email like the following:
Your account on <site-name> as been logged in on a new computer.
Date and Time: February 22, 2016, 2:10 PM EST
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.116
IP Address: ::1
If the information above looks familiar, you can disregard this email.
If you have not signed in to <site-name> recently and believe someone may have accessed your account, login to <site-name> and change your password as soon as possible.
