Vigor2960/3900/300B support two-factor authentication to access WUI management since firmware version 1.5.0. This article demonstrates how to set up 2-Step Authentication for the router's management, and add a layer of security to the router. When 2-Step Authentication is enabled, the user will not only need the administrator password but also the Auth-Code sent to the specific receiver, to log into the router's management page.
Note: It's recommended to enable 2FA on one interface or additional Admin user first, and apply the setting to all interfaces or Admin users after verification.
1. Go to System Maintenance>>Administrator Password>>Administrator Advanced Authentication, and select the interface where the user logs in requires two-factor authentication.

2. Go to Objects Setting>>Mail Service Object, and add a profile.
3. Back to System Maintenance>>Administrator Password>>Administrator Advanced Authentication, and enable Two-FA via Mail, and set receiver mail address
4. Login router WUI by admin password, next we will need to enter additional code to login from the authentication mail.
Note: Please make sure the time setting is correct on the router and mobile device.
5. Go to System Maintenance>>Administrator Password>>Administrator Advanced Authentication, and enable Two-FA via TOTP, click Generate Code, then click Apply.
