Learn how UserLock VPN Connect improves VPN logon experience and MFA reliability for Windows users. This page describes its purpose, features, configuration options, and user interface.

Published October 15, 2025

Overview

Without UserLock VPN Connect, users protected by UserLock can connect through standard VPN clients, but the MFA process depends on each client’s capabilities. This often leads to:

  • inconsistent workflows,

  • confusing prompts,

  • connection failures due to timing or input errors.


👉️ UserLock VPN Connect integrates MFA directly into the Windows VPN logon dialog, providing a consistent, one-step experience.

Users can connect to a VPN protected by UserLock in three different ways.

Limitations

VPN client with RADIUS Challenge

MFA handled in two steps: after credentials, a challenge requests the OTP code.

Clear MFA separation, reliable experience (if supported).

Requires VPN client compatibility with RADIUS Challenge.

  • Validating MFA before the VPN tunnel is created, preventing failed or dropped connections.

  • Allowing users to enroll MFA remotely through the UserLock IIS web page.

  • Supporting multiple VPN profiles with centralized GPO configuration.

  • Providing clear, detailed messages for easier troubleshooting.
