Technology Wisdom

TW Login Alert & Tracker is a lightweight yet powerful plugin designed to help administrators monitor login activity and enhance site security. 
It automatically tracks every user login and saves the date/time to their profile. A new “Last Login” column appears in the WordPress Users list, helping you quickly view user activity. 
The plugin also sends real-time email notifications to the site administrator each time a user logs in, including when the admin logs in. You now have full control over these alerts with a dedicated Settings page where you can enable or disable email notifications as needed. 
No configuration is required on activation. However, the Login Alert Settings page (under Settings) gives you the flexibility to toggle notifications anytime.
