Two-Factor Authentication for Windows VPN

miniOrange provides a ready to use 2FA solution for Windows VPN (PPTP) Platform. This solution ensures that you are ready to roll out secure access to Windows VPN to your employees within minutes.

Windows VPN 2FA/MFA

miniOrange Windows VPN 2FA solution supports the use of PAP Authentication with PPTP, SSTP, and L2TP VPN. A Windows PPTP client will not negotiate MPPE (encryption) when PAP is used, meaning the password is sent from the client to the RRAS server as plain text. miniOrange recommends SSTP or L2TP, which encrypt communication between the client and the RRAS server.
When you enable 2FA for Windows VPN, your users enter their username and password (first factor) as usual, and they have to enter an authentication code (the second factor) which will share on your virtual or hardware 2FA solution to get access.


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 Windows 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.


MFA 2FA Two-Factor authentication for Windows VPN

1. Primary authentication initiates with the user submitting his Username and Password.

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.


The following 2FA methods are supported for Windows VPN:
  • miniOrange Authenticator (Mobile Token, Push)
  • Google Authenticator
  • Microsoft Authenticator
  • Yubico OTP (hardware key authentication)
  • Out Of Band SMS/EMAIL
You can opt for any of the 2FA methods to secure your Windows VPN. To integrate 2FA, you can enable RADIUS authentication in Windows VPN and configure policies in miniOrange to enable or disable 2FA for users.

We can connect with any Directory

miniOrange provides user authentication from external directories like Microsoft Active Directory, Azure AD, AWS Cognito etc.
