Bank-Grade Privacy for Your Links
Not all QR codes are meant for the whole world to see. Whether you are sharing pre-release product specs, internal company memos, or exclusive VIP invitations, you need a layer of security that goes beyond a standard scan.
QR Lynx Password Protection acts as a secure gatekeeper. When a user scans your code, they are directed to a branded security page where they must enter the correct password before being redirected to your actual content.
This feature ensures that even if your QR code is shared publicly or photographed by unauthorized parties, the content behind it remains safe and inaccessible without the key.

Security FAQs
Common questions about secured QR codes.
How does the password protection work?
When a user scans your QR code, they are first taken to a secure landing page hosted by QR Lynx. This page prompts them to enter the password you set. Only after entering the correct password are they redirected to your actual destination URL or file.
Is this feature available on the Free plan?
No, Password Protection is an advanced security feature available on our Business and Enterprise plans. It requires Dynamic QR code functionality.
Can I change the password after printing?
Yes! Because the QR code is Dynamic, you can log in to your dashboard and update the password at any time. The physical QR code remains the same, but the access requirement changes immediately.
What happens if I forget the password?
As the account owner, you can always see and reset the password in your dashboard. If a user loses the password, you will need to communicate it to them again via a secure channel.
Is the content encrypted?
The connection to our password page is secured via SSL/HTTPS. The password itself is verified server-side before any redirect occurs, ensuring the destination URL remains hidden from casual snooping.
Does it work on all smartphone cameras?
Yes. The password protection happens on a web page displayed in the phone's browser after scanning. It is compatible with any device that can scan a standard QR code and browse the web.
Can I remove the password later?
Absolutely. If your content becomes public (e.g., after a product launch date), you can simply disable the password feature in your dashboard, and the QR code will behave like a standard link.
Can I see who tried to access it?
You can see analytics for the number of scans. While we track successful scans, detailed 'failed attempt' logs are an Enterprise-grade feature coming soon.
What kind of information can I protect with a password-protected QR code?
You can protect virtually any type of content behind a password-gated QR code, including confidential documents, private event details, exclusive discount pages, internal company resources, and restricted file downloads. QRLynx's password protection works with all dynamic QR code types, so whether your destination is a URL, PDF, or vCard, you can add an access gate to keep it secure.
How secure are password-protected QR codes?
QRLynx's password protection uses server-side verification over an SSL-encrypted connection, meaning the destination URL is never exposed in the QR code itself or transmitted before authentication. The password gate runs on our secure infrastructure, and the destination remains hidden until the correct password is entered. For maximum security, use a strong alphanumeric password and change it periodically.
Are there any limitations or downsides to using password-protected QR codes?
The main trade-off is an extra step in the user experience, since scanners must enter a password before reaching the content. This adds friction that can reduce conversion rates for marketing campaigns, so password protection is best suited for confidential or restricted content rather than public promotions. QRLynx makes the password page fast and mobile-friendly to minimize this friction as much as possible.
How often should I change the passcode for my QR code?
The frequency depends on your use case and security requirements. For highly sensitive content, consider rotating the password monthly or after each event. For general access control, changing it quarterly is usually sufficient. QRLynx makes password changes instant from your dashboard, and since the QR code is dynamic, you never need to reprint anything when you update the password.
