23.4 Two-Factor Authentication Overview
Use two-factor authentication to have double-layer security to access a secured network behind the
Zyxel Device via Web Configurator or SSH.
The first layer is the Zyxel Device’s login user name / password and the second layer is an authorized SMS
(via mobile phone number) or email address.
This section introduces how two-factor authentication works.

authenticate this admin user.
