General Description

Add Two-Factor Authentication, Passwordless Authentication and Account Validation to your WordPress website.

Overview

This plugin adds the following major features to WordPress:

• 3 One-Time Password modes: Two-Factor Authentication, Passwordless Authentication and Account Validation.
• 3 Authentication Gateways for OTP Verification Codes: WordPress Email, Twilio SMS, Alibaba Cloud SMS ; all with option to use a sandbox mode.
• Two-Factor Authentication: allow (or force) users to authenticate with a second factor on top of their password.
• Passwordless Authentication: allow users to login simply with their username, an identifier, and an OTP Verification Code (identifier depending on the Authentication Gateway - email or phone number supported with the default gateways).
• Account Validation: force users to validate their account by entering an OTP Verification Code at first login, on a set regular basis at login, or at each login.
• Synchronize OTP identifiers with existing data: wish to use Twilio SMS, but already have a phone number field saved in database? Perhaps with the "Billing Phone" in WooCommerce? Use this field by indicating its user meta key in the gateway settings (Note: duplicate identifiers will require users to choose a different one on update).
• Simple yet customizable appearance: forms used to request OTP Verification Codes use a neutral dedicated style compatible with most themes, with customizable logo and call-to-action colors.
• Activity Logs: when enabled, administrators can follow the activity of the enabled gateway. Critical messages regarding gateway malfunction are always logged.
• Customizable for developers: developers can add their own gateways or add custom One-Time Password modes using action and filter hooks, and more - see the developers documentation.
• Integration-friendly: specific integration with Ultimate Member and WooCommerce is included by default ; developers can easily plug into OTP Authenticator with a multitude of functions, filter hooks and action hooks - see the developers documentation - contributions to integrations are welcome.
• Unlimited features: there are no premium version feature restrictions shenanigans - OTP Authenticator is fully-featured right out of the box.

Adding an Authentication Gateway

** COMING SOON - WORK IN PROGRESS **

Developers can extend the plugin and add their own Authentication Gateway by using a few filter and action hooks as well as a class inheriting Otpa_Abstract_Gateway.
Below is a simple example of implementation of a Custom Authentication Gateway sending OTPs to the Activity logs (forced even if not enabled).

Implementing filter and actions hooks and including a custom Authentication Gateway class

** COMING SOON - WORK IN PROGRESS **

In this example, we are first creating a simple plugin to implement the action and filter hooks, and include the Authentication Gateway class.

<?php
/*
Plugin Name: Example of Authentication Gateway for OTP Authenticator
Version: 1.0
Text Domain: my-domain
*/

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

if ( ! defined( 'OTPA_CUSTOM_GATEWAY_PLUGIN_PATH' ) ) {
    define( 'OTPA_CUSTOM_GATEWAY_PLUGIN_PATH', plugin_dir_path( __FILE__ ) );
}

if ( ! defined( 'OTPA_CUSTOM_GATEWAY_PLUGIN_URL' ) ) {
    define( 'OTPA_CUSTOM_GATEWAY_PLUGIN_URL', plugin_dir_url( __FILE__ ) );
}

// COMING SOON

Implementing a custom Authentication Gateway class - example

The custom Authentication Gateway's logic is then implemented in the file class-otpa-custom-gateway.php included by the plugin.

<?php

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

class Otpa_Custom_Gateway extends Otpa_Abstract_Gateway {

    /*******************************************************************
     * Public methods
     *******************************************************************/

    // COMING SOON 

    /*******************************************************************
     * Protected methods
     *******************************************************************/

    // COMING SOON
}
