Loggedin is a lightweight WordPress plugin that lets you easily limit the number of simultaneous active sessions a user can have. This is a crucial feature for membership sites, online courses, and other platforms where you need to prevent users from sharing their accounts.
<h3>🎁 Features</h3>
<ul>
<li>Set Global Limits: Define a maximum number of concurrent logins for all users.</li>
<li>Flexible Login Behavior: Choose to either block new logins when the limit is reached or automatically log out the oldest session to allow a new one.</li>
<li>Prevent Account Sharing: By limiting sessions, you can effectively stop users from sharing their login credentials with others.</li>
<li>Admin Control: Easily force log out a user from the admin dashboard, giving you full control over active sessions.</li>
<li>Developer-Friendly: The plugin is built with a hook-based architecture, making it highly customizable and extensible for developers.</li>
</ul>
