How to Self Enroll for Time-Based One-Time Passwords (TOTP) using the Simple TOTP Web Portal

  • Last updated on

To self-enroll for multi-factor authentication using Time-Based One-Time Passwords (TOTP) as a Remote Access user, log into the TOTP web portal, using the SSL VPN service listen IP address or URL that has been configured by the admin: https://(IP of the SSL VPN service)/portal/totp.html. Use the app of your choice that supports the TOTP protocol (e.g., Google Authenticator, Microsoft Authenticator, 1password, etc.) to enroll your account using either the QR code generated by the app or manually with the secret key.

Self-Enroll as a User

  1. Log into the TOTP web portal. The Time-based OTP > Enrollment window opens.
  2. Scan or click the QR code or enter the Secret Key into your TOTP app or plugin of choice.

  3. Enter the Verification Code generated by the app in the provided field.

  4. Click on the check mark in the top-right corner to complete the enrollment.

Your account is now linked with Time-Based One-Time Password Authentication on the CloudGen Firewall. You can now use the 6 digit TOTP codes for the SSL VPN web portal, CudaLaunch, and the Barracuda VPN Client for Windows.

Self Service as a User

  1. Log into the TOTP web portal. The Time-based OTP window opens.
  2. In the Time-based OTP popup, enter your verification code.
  3. Click Continue to start your self service session.

You can view/regenerate your backup codes. If you have been given permission, you can re-enroll.

Logging in Using Backup Codes

As soon as you are enrolled for multi-factor authentication using Time-based One-time Passwords, you can access backup codes that you can also use to log into the SSL VPN web portal or CudaLaunch, or to establish VPN connections using the Barracuda VPN Client for Windows. Backup can be used to access your account in place of a Time-based OTP verification code.

  • Each code can be used only once.
  • It is strongly recommended that you copy the backup codes and store them in a safe place.

To access the backup codes:

  1. Log into the TOTP web portal. The Time-based OTP window opens.
  2. In the left menu, select Backup Codes.
  3. Use the codes on the right side of the window to log in. To generate new codes, click Generate New Backup Codes.
