Upgrading your laptop, replacing a motherboard, or setting up a brand-new desktop computer is an exciting milestone. But with many premium software licenses, moving an activation to a new machine often turns into a tedious chore requiring support tickets, manual deactivation requests, and multi-day waiting periods.
At PrivaGuard, we engineered our licensing system around a fundamental principle: you own your license, and moving it to a new machine should take less than 60 seconds.
In this guide, we walk you through how PrivaGuard's 1-Click Migration Protocol works, how Hardware IDs (HWIDs) are bound, and how you can seamlessly activate your license across single, duo, or family device configurations.
You never have to email our helpdesk or submit a ticket to move your license. Device transfers are 100% automated via instant email authorization, backed by Paddle Merchant of Record buyer protection and a 14-day refund guarantee.
Step-by-Step: Moving Your License in 3 Simple Steps
To transfer your PrivaGuard license from an old computer to your new computer:
- Download & Install PrivaGuard: On your new computer, download the official setup package from privaguard.tech and launch the application.
- Enter Your License Key: Click "Activate PRO" on the main control center. Enter your original License Key (format:
PG-XXXX-XXXX-XXXX) and your registered purchase email address. - Verify 1-Click Migration OTP: PrivaGuard's backend will detect that this license was previously bound to another hardware profile. It immediately sends a 6-digit confirmation code to your email. Enter the code to confirm the transfer!
Open-Core Architecture & Licensing Separation
PrivaGuard publishes its core security modules publicly on GitHub. Commercial licensing is handled entirely through local cryptographic token signatures without telemetry trackers.

To prevent illegal software piracy without collecting invasive telemetry, PrivaGuard calculates a cryptographic one-way hash derived from your computer's motherboard UUID and CPU architecture:
- This hash (HWID) is completely non-reversible—it reveals zero personal details about your files, user accounts, or browsing habits.
- When your license activates, our Node.js RSA-2048 signing engine signs the license payload containing:
email | hwid | plan | expiry. - The client desktop application verifies this digital signature offline using an embedded RSA-2048 public key.
Single vs. Duo vs. Family License Limits
Depending on which plan you selected during checkout, PrivaGuard supports concurrent activations across multiple devices:
- Single Edition (1 PC): Ideal for personal workstations. Supports 1 active computer at a time. Activating on a new machine automatically releases the older machine.
- Duo Edition (2 PCs): Designed for power users with both a desktop PC and a portable laptop. Both devices run concurrently under the same license key with zero unbinding required.
- Family Edition (5 PCs): Maximum value for households and small businesses. Protects up to 5 Windows machines simultaneously.
