Multi-factor Authentication (MFA/2FA) for Array AG SSL VPN
Array SSL VPN appliances allow enterprises to consolidate remote access for employees, partners, users, and other communities of interest on a single platform to improve operational efficiency and provide a superior end-user experience. You can enable two-factor authentication (2FA) for your Array AG SSL VPN managed active directory to increase the security level. 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) for which they can use Google Authenticator, Microsoft Authenticator, OTP over SMS/Email , Push Notification, and many more. This 2FA/MFA solution adds an additional security measure to prevent unwanted users from getting access to your Array AG SSL VPN.
miniOrange MFA/2FA authentication for Array AG SSL VPN 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.
- Primary authentication initiates with the user submitting his Username and Password for Array AG SSL VPN.
- User request acts as an authentication request to RADIUS Server(miniOrange).
- miniOrange RADIUS server passes user credentials to validate against the credentials stored in AD (Active Directory) / Database.
- Once the user's first level of authentication gets validated AD sends the confirmation to RADIUS Server.
- Now miniOrange RADIUS Server asks for a 2-factor authentication challenge to the user.
- Here user submits the response/code which he receives on his hardware/phone.
- User response is checked at miniOrange’s RADIUS Server side.
- On successful 2nd factor authentication the user is granted access to login.
Connect with any External Directories

Frequently Asked Questions (FAQs)
What is Multi-Factor Authentication (MFA)?
Multi-Factor Authentication (MFA) is an authentication method that requires the user to authenticate themselves for two or more factors, in order to gain access to company resources, applications, or a VPN (Array AG SSL VPN in this case). Enabling Multi-Factor Authentication (MFA) means that users need to provide additional verification factors apart from their username and passwords thus increasing the security of the organization's resources. Checkout more about Multi-Factor Authentication (MFA) here.
Three common authentication methods for MFA security are:
- Knowledge: Something that the user knows.
- Possession: Something that the user possesses or has.
- Inherence: Usually referred to a biometric factor.
Types of 2FA Authentication with RADIUS:
Depending on the VPN client, 2-factor authentication can take two forms..
- VPN Clients that support RADIUS Challenge.
- VPN Clients that do not support RADIUS Challenge.
