== Frequently Asked Questions ==

= Can I still allow concurrent logins for certain users? =

Yes, you can do this by using the `pcl_prevent_concurrent_logins` filter:

<pre lang="php">
function pcl_bypass_admins( $user_id ) {
    $user = get_user_by( 'id', absint( $user_id ) );

    if ( ! empty( $user->roles[0] ) && 'administrator' === $user->roles[0] ) {
        return false;
    }

    return true;
}
add_filter( 'pcl_prevent_concurrent_logins', 'pcl_bypass_admins', 10, 1 );
</pre>
