Customise error message

Hello All,

I found the solution for the same. This plugin use the default WordPress error. so, you can use below code for change message in the API response. I got the success in this. Hope it’s help to you too!!

remove_filter( 'authenticate', 'wp_authenticate_username_password' );
add_filter( 'authenticate', 'wpse_115539_authenticate_username_password', 20, 3 );
/**
 * Remove WordPress filer and write our own with changed error text.
 */
function wpse_115539_authenticate_username_password( $user, $username, $password ) {
    if ( is_a($user, 'WP_User') )
        return $user;

    if ( empty( $username ) || empty( $password ) ) {
        if ( is_wp_error( $user ) )
            return $user;

        $error = new WP_Error();

        if ( empty( $username ) )
            $error->add( 'empty_username', __('<strong>ERROR</strong>: The username field is empty.' ) );

        if ( empty( $password ) )
            $error->add( 'empty_password', __( '<strong>ERROR</strong>: The password field is empty.' ) );

        return $error;
    }

    $user = get_user_by( 'login', $username );

    if ( !$user )
        return new WP_Error( 'invalid_username', sprintf( __( '<strong>ERROR</strong>: Invalid username. <a href="%s" title="Password Lost and Found">Lost your password</a>?' ), wp_lostpassword_url() ) );

    $user = apply_filters( 'wp_authenticate_user', $user, $password );
    if ( is_wp_error( $user ) )
        return $user;

    if ( ! wp_check_password( $password, $user->user_pass, $user->ID ) )
        return new WP_Error( 'incorrect_password', sprintf( __( '<strong>ERROR</strong>: The password you entered for the username <strong>%1$s</strong> is incorrect. <a href="%2$s" title="Password Lost and Found">Lost your password</a>?' ),
        $username, wp_lostpassword_url() ) );

    return $user;
}
