Zyxel Single Sign-On with Microsoft Entra ID for Zyxel Account

We're excited to announce a powerful new feature for Zyxel Account users! Now you can streamline your login experience with Microsoft Entra ID integration, enabling Single Sign-On (SSO) across all Zyxel platforms. This seamless authentication method eliminates the need for separate passwords while enhancing security through your organization's identity management system.

This guide explains how to configure Microsoft Entra ID (formerly Azure AD) as an Identity Provider (IdP) for Zyxel Account, making authentication simpler and more secure for your entire organization.

Key Benefits of Microsoft Entra ID Integration

✓ Enhanced Security: Leverage Microsoft's robust identity verification systems
✓ Streamlined Access: One-click login across all Zyxel platforms
✓ Simplified Management: Centralized user administration through your Microsoft environment
✓ Reduced Password Fatigue: No more separate Zyxel Account passwords to remember
✓ Improved Compliance: Better audit trails and access controls

Important to Know Before You Begin

Settings

1. Each domain can only be configured with one set of Entra ID settings to ensure consistent authentication and access control across your organization.

2. Once an Entra Application ID configuration is verified for a domain, any identical Entra Application ID and domain pairs will be blocked and removed.

3. Once IT completes the Entra ID configuration, all users within the same domain will automatically transition to 'Continue with Microsoft Entra ID' as their authentication method.

For New User

1. When a new user from a configured domain successfully signs in with Entra ID for the first time, a Zyxel Account will be automatically created.

2. When users from a configured domain attempt to sign in through non-Entra ID methods, they will receive an email notification informing them that 'Continue with Microsoft Entra ID' is the exclusive authentication method for their organization.

3. Once the IT team completes the Entra ID configuration, it will be the only login method for the company domain. Users will no longer have the option to log in using conventional username and password combinations.

For IT

1. IT should not use delegate email or shared email address, which doesn't have password, to process Entra ID settings as it will encounter issues during the testing phase.

2. For IT to disable Entra ID after deployment, please follow the EITS process to submit a ticket.

3. For IT to change the email address, please follow the EITS process to submit a ticket.
