            type: 'POST',
            dataType: 'json',
            url: ajax_login_object.ajaxurl,
            data: { 
                'action': 'ajaxlogin', //calls wp_ajax_nopriv_ajaxlogin
                'username': $('form#login #username').val(), 
                'password': $('form#login #password').val(), 
                'security': $('form#login #security').val() },
            success: function(data){
            	if(data.loggedin == false){
            		$('form#login p.status').html("<div class='choko_login_error_msg'>"+data.message+"</div>");
            	}else{
            		$('form#login p.status').html(data.message);
            	}
                if (data.loggedin == true){
                    document.location.href = ajax_login_object.redirecturl;
                }

In your function.php file put the below ajax code for login.

function ajax_login_init(){

    wp_register_script('ajax-login-script', get_template_directory_uri() . '/ajax-login-script.js', array('jquery') ); 
    wp_enqueue_script('ajax-login-script');

    wp_localize_script( 'ajax-login-script', 'ajax_login_object', array( 
        'ajaxurl' => admin_url( 'admin-ajax.php' ),
        'redirecturl' => home_url(),
        'loadingmessage' => __('Sending user info, please wait...')
    ));

    // Enable the user with no privileges to run ajax_login() in AJAX
    add_action( 'wp_ajax_nopriv_ajaxlogin', 'ajax_login' );
}

// Execute the action only if the user isn't logged in
if (!is_user_logged_in()) {
    add_action('init', 'ajax_login_init');
}

function ajax_login(){

    // First check the nonce, if it fails the function will break
    check_ajax_referer( 'ajax-login-nonce', 'security' );

    // Nonce is checked, get the POST data and sign user on
    $info = array();
    $info['user_login'] = $_POST['username'];
    $info['user_password'] = $_POST['password'];
    $info['remember'] = true;

    $user_signon = wp_signon( $info, false );
    if ( is_wp_error($user_signon) ){
        echo json_encode(array('loggedin'=>false, 'message'=>__('Wrong username or password.')));
    } else {
