Configure Multifactor Authentication (MFA/2FA) for VMware Horizon View (VDI)

miniOrange strengthens the security of VMware Horizon 2-factor Authentication (2FA) or VMware Horizon View MFA . This advanced approach requires not only your regular password but an additional piece of information it's like having a second lock on your Horizon account, making it exceptionally tough for unauthorized access.

miniOrange seamlessly integrates this added security layer into the VMware Horizon login process. Even if someone discovers your password, they can't get in without the second level of authentication, which can be generated by tools such as Google Authenticator. This extra layer of security, known as VMware Horizon MFA or VMware Horizon Two-factor authentication helps ensure your sensitive data stays well-protected in line with the latest security standards.

To use miniOrange Multi-Factor Authentication (MFA) or Two-factor Authentication you can enable RADIUS authentication in VMware Horizon View and configure policies in miniOrange to enable or disable MFA for users. miniOrange provides 15+ Multi-Factor Authentication methods to secure your network.

Types of two-factor authentication - 2FA with RADIUS

Two-factor authentication (2fa) can be of two types depending on the Application you want to enable it for.

  • Applications that support RADIUS Challenge.
  • Applications that do not support RADIUS Challenge.

In Applications that support RADIUS Challenge :

  • The first step involves validating the user's username and password against the credentials stored in Active Directory. Once this authentication is successful, a second request is sent to confirm the user's two-factor authentication. Upon successful authentication, the user is granted access to the application.
  • Authentication methods : miniOrange offers support for a wide array of authentication methods, encompassing options like Google Authenticator, Software Tokens, Push Notifications, and OTP over Email, among others.

  • For RADIUS authentication, follow the vendor's configuration documentation. Please make a note of the RADIUS server's hostname or IP address, the port number on which it is listening for RADIUS authentication (usually 1812), the authentication type (PAP, CHAP, MS-CHAPv1, or MS-CHAPv2), and the shared secret. You will enter these values in Horizon Administrator. You can enter values for a primary and a secondary RADIUS authenticator.
