Last User Login

This module adds a "Last Login" column to the Network Admin > Users screen in WordPress Multisite. It records and displays the last time each user logged into the network, helping administrators better understand user activity.

Features

• Adds a "Last Login" column to the Network Users list.
• Automatically stores the login timestamp when users authenticate.
• Makes the column sortable by login date.
• Dates are displayed using the site's configured date format.
• Timezone-aware display with ISO 8601 tooltips.
• Shows "Never" for users who have not yet logged in.

How It Works

• Whenever a user logs in, the timestamp is saved in UTC in user meta (last_logged_in).
• A new column (Last Login) appears in the Network Admin > Users table.
• The column displays the date formatted according to the site's links_updated_date_format setting, with the full timestamp shown in a tooltip.
• The column is also sortable, and users without login data are treated appropriately.

Technical Details

• Column Key: last-logged-in
• Meta Key: last_logged_in
• Date Format: Stored as Y-m-d H:i:s (UTC), displayed using WordPress date format settings.
• Permissions: Only visible to users with list_users capability.

Use Cases

• Identify inactive users across the network.
• Improve network management by sorting users by activity.
• Audit logins for security or engagement tracking.
