Two Factor Authentication

ROUNDCUBE PLUS TWO-FACTOR AUTHENTICATION PLUGIN =============================================== This plugin adds two-factor authentication to Roundcube. REQUIREMENTS ------------ - Roundcube: 1.5, 1.6 - PHP: 7.4 or higher - PHP cURL extension INSTALLATION ------------ 1. Copy the directories x2fa and xframework included in this package to the 'plugins' directory of your Roundcube installation. 2. Rename the file <roundcube>/plugins/x2fa/config.inc.php.dist to config.inc.php. 3. Edit the file <roundcube>/plugins/x2fa/config.inc.php and modify the settings according to your needs. 4. Edit the file <roundcube>/config/config.inc.php, add x2fa to the plugins array and specify your license key. For more information on installing Roundcube Plus plugins see: https://roundcubeplus.com/helpdesk/knowledgebase.php?article=29 AUTHENTICATION METHODS ---------------------- The x2fa plugin supports four authentication methods. TOTP, email, SMS, and Yubikey. TOTP and email work out of the box and require no configuration. SMS and Yubikey require obtaining API credentials and placing them in the config.inc.php file. THE TOTP AUTHENTICATION METHOD ------------------------------ Although this method requires no configuration, you should make sure that your server's time is set correctly. The time on the server and on the smartphone that generates the authentication code must be synchronized, otherwise the authentication will not work and you'll keep getting the message: "Incorrect or expired authentication code." THE SMS AUTHENTICATION METHOD ----------------------------- After an extensive research we have implemented support for two SMS providers: Bulkgate and D7networks. These providers offer a reliable service with a worldwide coverage at a relatively low price. Their accounts are easy to configure and top up and they offer a few free SMSs that you can send before making any payments. SMS METHOD: BULKGATE -------------------- 1. Create an account here: https://portal.bulkgate.com/join/49082 2. Log in to your new account and navigate to "Modules and APIs" on the sidebar. 3. If you're here for the first time, click "SimpleAPI" and then click Create API. If you have created this API before, you will see it at the top of the page in the section "My APIs and Modules". Click to open it. 4. On the SimpleAPI page you will see the Application ID and Application token that you will need to enter in the x2fa config file. Edit x2fa/config.inc.php and fill the SMS settings this way: $config['x2fa_sms_provider'] = 'bulkgate'; $config['x2fa_sms_api_id'] = 'your_application_id_here'; $config['x2fa_sms_api_token'] = 'your_application_token_here'; SMS METHOD: D7NETWORKS ---------------------- 1. Create an account here: https://d7networks.com 2. Log in to your new account and copy the SMS API Token shown on the dashboard page. 4. Edit the file x2fa/config.inc.php and fill the SMS settings this way: $config['x2fa_sms_provider'] = 'd7networks'; $config['x2fa_sms_api_token'] = 'your_sms_api_token_here'; THE YUBIKEY OTP AUTHENTICATION METHOD ------------------------------------- Yubikeys provide support for multiple authentication protocols. The "Yubikey" authentication implemented in this plugin uses the OTP protocol. Please note that not all Yubikey models support the OTP protocol. For the list of all the Yubico keys and their descriptions, see https://www.yubico.com/products In order to use Yubikey OTP authentication, you'll need a client ID and secret key from Yubico. You can get them for free from: https://upgrade.yubico.com/getapikey CURL SUPPORT ------------ The SMS and Yubikey methods use cURL to communicate with the third-party API servers. In order to use those methods the cURL PHP extension must be installed on your server. (It is installed by default on most servers.)
