Two-Factor Authentication (2FA/MFA) for Fortinet Fortigate VPN


Fortinet Fortigate managed FortiClient can be used as a VPN Client (IPSec and SSL), an AV client and a host vulnerability scanner. Forticlient is used as the corporate AV solution and for VPN remote access. It works on Windows and Mac but there's no Linux version. If your user wants remote access to their office then FortiClient would be a good solution.

Enabling Two-Factor Authentication(2FA) for your Fortinet Fortigate managed active directory increases security and ensures users only have access to the systems and resources they need access to. When you enable 2FA, your users enter their username and password (first factor) as usual, and they have to enter an authentication code (the second factor) which will be shared on their virtual or hardware 2FA solution to get access to Forticlient VPN.


Types of 2FA Authentication with RADIUS

The 2-factor authentication can be of two types depending on the VPN clients.

  • VPN Clients that support RADIUS Challenge.
  • VPN Clients that do not support RADIUS Challenge.

miniOrange 2FA authentication for Fortinet Fortigate Login

miniOrange accomplishes this by acting as a RADIUS server that accepts the username/password of the user entered as a RADIUS request and validates the user against the user store as Active Directory (AD). After the first level of authentication, miniOrange prompts the user with 2-factor authentication and either grants/revokes access based on the input by the user.


MFA 2FA Two-Factor authentication for Fortinet

  1. Primary authentication initiates with the user submitting his Username and Password for Fortinet Fortigate.
  2. User request acts as an authentication request to RADIUS Server(miniOrange).
  3. miniOrange RADIUS server passes user credentials to validate against the credentials stored in AD (Active Directory) / Database.
  4. Once the user's first level of authentication gets validated AD sends the confirmation to RADIUS Server.
  5. Now miniOrange RADIUS Server asks for a 2-factor authentication challenge to the user.
  6. Here user submits the response/code which he receives on his hardware/phone.
  7. User response is checked at miniOrange’s RADIUS Server side.
  8. On successful 2nd factor authentication the user is granted access to login.

What are different 2FA/MFA methods for Fortinet Fortigate supported by miniOrange?

miniOrange supports multiple 2FA/MFA authentication methods for Fortinet Fortigate secure access such as, Push Notification, Soft Token, Microssoft / Google Authenticator etc.
