Sends a detailed notification email when admins and other users log in to your site. Choose the user levels/roles for which you would like to receive login notifications. Optionally exclude users and/or IP addresses.
This plugin is useful for keeping an eye on any unauthorized administrator or user logins. Each email alert includes the user name, IP address, user agent, and other details. Very useful for forensic investigations.

Why is this useful?
I use this plugin to keep an eye on any unauthorized login attempts. Probably a bit paranoid but I don’t care, paranoid works well for me.
How is this plugin different?
While researching for this plugin, I found four other “admin login notification” type plugins:
<ul>
<li><a href="https://wordpress.org/plugins/email-notification-on-login/" rel="ugc">Email Notification on Login</a></li>
<li><a href="https://wordpress.org/plugins/email-notification-on-admin-login/" rel="ugc">Email notification on admin login</a></li>
<li><a href="https://wordpress.org/plugins/kaya-login-notification/" rel="ugc">Kaya Login Notification</a></li>
<li><a href="https://wordpress.org/plugins/kolorweb-access-admin-notification/" rel="ugc">KolorWeb Access Admin Notification</a></li>
</ul>
Unfortunately none of these plugins suited my specific needs:
<ul>
<li>Lightweight, clean and simple</li>
<li>Current with latest WordPress</li>
<li>No requirement for PHP sessions</li>
</ul>
So I decided to build my own. Let me emphasize the utter simplicity of this plugin. It does one thing and does it well: sends an email whenever an admin-level user logs in to WordPress. No bells and whistles, no bloat. If you need more functionality, check out the above plugins should get you there.
Privacy
This plugin does not collect or store any user data. It does not set any cookies, and it does not connect to any third-party locations. The only thing this plugin does is send an email for each admin-level login. Each email includes information about the user, such as username, IP address, user agent, and other details.

This plugin sends an email to the WordPress System email (Settings / General / Email Address) or any other configured email address each time somebody logs into WordPress. This is handy if there are not many logins each day or week to keep track of all of them and being able to detect non authorized logins.
The email contains the username, the user id and the user role (administrator, editor, author or contributor). Other data included is the Date & Time and the IP Address.
This plugin is an enhanced version of the plugin <a href="https://wordpress.org/plugins/email-notification-on-admin-login/" rel="ugc">Email notification on admin login</a>, that tracks all users, includes user role, translations and the lookup of the country of the IP from which the form is sent.
We created this enhanced version of the plugin, because we needed a translation to Spanish and wanted to know the country from which the uses send the contact form, whithout having to lookup the IP address.
In order to display the Country it needs the <a href="https://wordpress.org/plugins/geoip-detect/" rel="ugc">Geolocation IP Detection (until March 2020: GeoIP Detection) plugin</a> that can be found in the WordPress plugin repository. This plugin “provides geographic information detected by an IP adress”. This plugin auto-updates the GeoIP database once a week. This product includes GeoLite data created by MaxMind, available from <a href="http://www.maxmind.com" rel="nofollow ugc">www.maxmind.com</a>.
If the <a href="https://wordpress.org/plugins/geoip-detect/" rel="ugc">Geolocation IP Detection (until March 2020: GeoIP Detection) plugin</a> is not installed and enabled, you will only see the IP address, without the country of the IP adress.
We decided to use the Geolocation IP Detection (until March 2020: GeoIP Detection) plugin to handle the lookup of the country, because it’s a plugin that is actively developed and we saw no advantage in implementing all this functionality, when we could use an existing one.
