To resolve this, you'll need to bind your NetExtender account with the Microsoft Authenticator app on your mobile device. Here's a step-by-step guide:


1. Access the SonicWall Portal:

  • Enable this feature and select "Microsoft Authenticator" as your preferred authentication method.


5. Set Up Microsoft Authenticator:

  • Download the App: If you haven't already, download the Microsoft Authenticator app from your device's app store (App Store for iOS, Google Play Store for Android).

  • Add an Account: Open the app and tap the "+" button to add a new account.

  • Scan the QR Code: You'll be prompted to scan a QR code displayed on the SonicWall portal screen. Use your device's camera to scan this code.

6. Log In to NetExtender:

  • Launch the NetExtender app on your computer.

  • Enter your NetExtender credentials when prompted.

  • You'll be asked to provide a one-time password.
