Limit Access WP Plugin

Установка

1. Install the plugin via automatic method or manual upload method
   1. Create a new page with a slug name: «limited-access»;
   2. Edit this «limited-access» page to have a message for the user for when they get logged out.
   3. Activate the plugin.
   4. Congrats you’re done!

Example:

Settings:  $allowedIPs = 3;

The account, "test_user" can be logged in from 3 different IPs, but when the fourth instance is accessed, the user will be logged out and redirected to a page explaining what happened. 

You have the ability to change the number of allowed IPs, the time each record is stored in the database, and if there are special circumstances for certain users.

Lines for settings:

To change the allowed number of IPs:        line 9;
To change the time each record is stored:       line 21;
To alter special circumstances, per user:       line 44 - 50;

You can add multiple special users by using the OR operator. Eg:

    if ( $user_login == 'admin' || $user_login == 'joe' ) {
        exit;
    }
