Enable secure mode and qr2desk scrambles your scan result the moment it leaves your phone. Nobody in between — no server, no cloud — can read it. Only your PC unlocks it.
The secret key travels only via the QR code — every computer in between sees only scrambled data.
With secure mode on, any computer in between only sees scrambled, unreadable data — like a sealed envelope that only you can open.
| Normal mode | Secure mode 🔒 | |
|---|---|---|
| Transfer server | https://beispiel.de/angebot/diese-woche | 🔒 Scrambled — unreadable |
| Your PC | https://beispiel.de/angebot/diese-woche | https://beispiel.de/angebot/diese-woche |
Everything happens automatically. You just flip a switch.
The moment you enable secure mode, your browser quietly creates a unique secret key. It never leaves your device — not even for a millisecond.
The QR code on your screen carries this secret key. Your phone receives it by simply scanning the screen. No network involved — the key moves from screen to camera.
After scanning your QR code, your phone immediately scrambles the result using the secret key — before anything is sent. What leaves your phone is unreadable to anyone else.
The scrambled data arrives on your PC. Your browser uses the original key — still stored only locally — to restore the readable content. No other device was ever involved.
A link to an X-ray report or lab result travels to your PC without any cloud service reading or storing it along the way.
Scan a QR code from your password manager and transfer the credentials without them passing through any server in readable form.
Company intranet, VPN access codes, or internal tools — transferred privately, without any third-party cloud knowing the address.
Two-factor codes, one-click login links, or temporary access codes — transferred without any middleman seeing them.
Here is exactly what happens under the hood — open, verifiable, no black box.
Open qr2desk, flip the secure mode switch — everything else works exactly as before.
