What you scan
stays between you and your PC.

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.

What happens to your data along the way

With secure mode on, any computer in between only sees scrambled, unreadable data — like a sealed envelope that only you can open.

How secure mode works

Everything happens automatically. You just flip a switch.

1

A secret key is created on your PC

The moment you enable secure mode, your browser quietly creates a unique secret key. It never leaves your device — not even for a millisecond.

2

The key travels via the QR code — not the internet

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.

3

Your phone scrambles the data before sending

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.

4

Only your PC can unscramble it

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.

Who benefits from secure mode

🏥

Medical document links

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.

🔑

Passwords & login codes

Scan a QR code from your password manager and transfer the credentials without them passing through any server in readable form.

🏢

Internal work links

Company intranet, VPN access codes, or internal tools — transferred privately, without any third-party cloud knowing the address.

📋

One-time codes & access links

Two-factor codes, one-click login links, or temporary access codes — transferred without any middleman seeing them.

For the technically curious

Here is exactly what happens under the hood — open, verifiable, no black box.

Encryption standardAES-256-GCM — the same algorithm used by banks and governments worldwide
Secret keyGenerated fresh for every session, never transmitted over the network
Key transportEmbedded in the QR code URL hash — a part of the URL that browsers never send to servers
ImplementationBuilt on the browser's built-in cryptography — no third-party code involved
What is storedOnly the scrambled data — the original content is never saved anywhere
Key lifetimeExists only in your browser memory, gone when you close or reload the page
