Passwords remain the primary method of authentication, but they are vulnerable: easy to guess, often reused across services, and frequent targets of attacks. To improve security, two-factor authentication (2FA) and multi-factor authentication (MFA) are widely used. The next step is passkeys — a technology that eliminates passwords entirely while providing stronger and more convenient protection.
This article explains how 2FA, MFA, and passkeys work, their advantages, and their role in the future of authentication.

Please Note: To access Zyxel services, you have two authentication options: Google or Apple authentication, or the traditional method of using an email and password. Each method has its own procedure for enabling two-factor authentication (2FA). If you choose to log in using your email and password, you have the ability to set up 2FA directly within your Zyxel personal account settings. Which we will discuss in this article. |
You can configure two options for two-factor authentication. The first one with sending a confirmation code via email and the second one with using the two-factor authentication mobile app.
