Workaround

Use an open source Roundcube plugin like: alexandregz/twofactor_gauthenticator

Use these steps to install the plugin in Plesk Roundcube:

Connect to the server via SSH
Go to Roundcube plugin folder:

# cd /usr/share/psa-roundcube/plugins
Clone the repository:

# git clone https://github.com/alexandregz/twofactor_gauthenticator.git
Edit Roundcube configuration file /usr/share/psa-roundcube/config/defaults.inc.php

# vi /usr/share/psa-roundcube/config/defaults.inc.php
Edit the plugin section and leave it like this:

// List of active plugins (in plugins/ directory)
$config['plugins'] = ['twofactor_gauthenticator', 'password', 'markasjunk', 'managesieve'];
Copy the configuration file:

# cp twofactor_gauthenticator/config.inc.php.dist twofactor_gauthenticator/config.inc.php
(Optional), open the configuration file and adjust if needed:

# vi twofactor_gauthenticator/config.inc.php

Note: For example, you can set force_enrollment_users to true to force all users to use 2FA.

Follow the instructions on git to configure 2FA
