Prevent Dial-up Password from being Saved using Intune

Dial-up Password from being Saved critical for hardening the Windows operating system against credential theft. The core purpose of this policy is to eliminate the local caching of network credentials used for Dial-up and Virtual Private Network (VPN) connections.

Without this policy, if a user selects “Save Password,” the credentials are encrypted and stored on the hard drive. If the device is lost or stolen, an unauthorized individual could potentially boot the laptop, click “Connect” on a saved VPN profile, and gain a direct tunnel into your corporate network without ever knowing the password.

Example Scenario

Imagine a sales rep working from a public Wi-Fi network at an airport. They use a Windows VPN (which uses the dial-up logic) to access the corporate CRM. Enabling this policy prevents the “Connect” button from working without a manual password entry, effectively stopping the thief at the perimeter.
