When a password-protected QR code makes sense
Everyone can see a printed QR code: whoever walks past the poster, whoever takes a photo of the invitation, whoever finds the card on a table. Usually that is the point. Sometimes, though, what is behind the code is meant only for certain people.
With a password, the QR code works like a door with a lock. Whoever scans it first sees a clean page in their language that asks for the password. You hand out the password however you like: at the entrance, in a message, written on the table. The destination appears nowhere before the right password is typed, neither on the page nor in its source.
Because the code is dynamic, you can change the password or the destination at any time without reprinting anything. With a new password, everyone who got in with the old one is asked again straight away.
What it protects
- It keeps the link away from people who merely found or photographed the QR code.
- The password is stored only as a hash, and attempts are limited.
- You see how many wrong attempts there were and, if you like, the code pauses itself.
What it is not
- It does not encrypt the content of the destination. Anyone who has the password can share the link.
- It is not a high-security system for medical, financial or other sensitive documents. Those also need a lock on the destination itself.

Frequently asked questions
Is the password safe?
It is stored only as a hash (Argon2id), like account passwords. Attempts are limited per device.
Do people type it every time?
No. The right password opens the link for 12 hours on the same device.
What if someone keeps guessing?
Attempts are limited and counted in the statistics. If you like, the code pauses itself after the number of wrong attempts you choose.
Can I remove the password later?
Yes, under “Rules & lock”. The code opens for everyone again at once.
Can someone see where the QR code leads without the password?
No. The password page does not contain the destination. The redirect only happens after the right password is typed.
Which language is the password page in?
In the code’s language, and visitors can switch to any of ThugQR’s 8 languages with one tap.
