Password Protected QR Code: How to Make One

A password protected QR code asks the person scanning it for a password before it opens the link or file behind it. The password is not stored in the printed pattern. The code is dynamic, so each scan goes to the QR service first, which shows a password prompt and only forwards people who enter the right one. On QRelix you create a QR code, switch on Password Protection in the Settings step, and type the password you want. Password protection is part of QRelix Pro at $5.99 per month. The free plan covers creating, designing, and tracking codes, with 50 scans per code and a brief QRelix screen on each scan.

How a password protected QR code works

A QR code is a pattern that stores a short piece of text, usually a web address. It cannot check a password by itself. The check happens online, after the scan.

• Someone scans the code with their phone camera.
• The phone opens the short link stored in the code. That link belongs to QRelix.
• QRelix shows a password prompt in place of your content.
• The correct password sends the scan on to your link or file. Anyone without it stops at the prompt.

Two things follow from this. Only a dynamic code can have a password, because a static code sends the phone straight to the destination with nothing in between. And the password can be added, changed, or removed after the code is printed, because it is a setting in your dashboard and not part of the printed squares. The static vs. dynamic comparison explains the two types.

How to make a QR code with a password

Step 1: Create the code

Sign in to QRelix and click Create New QR Code. Choose the type that matches what you are protecting: URL for a web page or a shared folder, File to upload a PDF or an image, or another type from the list.

Step 2: Turn on Password Protection

In the Settings step, switch Password Protection on and enter the password. This setting needs a Pro account.

Step 3: Design and download

Set your colors, add a logo if you want one, and generate the code. Download SVG for anything printed and PNG for slides, emails, and screens.

Step 4: Test it on a phone

Scan the printed or on-screen code with a phone. Check that the prompt appears, that a wrong password does not get through, and that the right one opens the destination.

Step 5: Share the password separately

Send the password by email, say it in the room, or print it on the ticket or the welcome sheet. A password printed right beside the code only keeps out people who are not paying attention. Pick one that is easy to say out loud and hard to guess, such as two unrelated words and a number.

Adding a password to a code you already printed

Open the code from your dashboard, click Edit, and set the password. The change applies to the next scan and the printed code does not change. Removing or replacing the password works the same way. How to edit a QR code after printing covers the other settings you can change on a printed code.

What to put behind a password

• Internal documents. A code on the break room wall opens the staff handbook or the shift schedule, and visitors who scan it see only the prompt.
• Event content. Print the code on badges or the closing slide and announce the password from the stage, so the slides and recordings go to people who attended. QR codes for event marketing has more event setups.
• Client deliverables. Proofs, quotes, and bid packages that should open for one client and nobody else who picks up the printout.
• Member resources. A member directory, training materials, or a partner price list.
• Files. A PDF you would not want indexed or passed around freely. How to make a QR code for a PDF explains the upload and link options.

A worked example

A general contractor posts one QR code at the site gate that opens the current drawing set. The code uses the URL type and points to a shared folder. Subcontractors get the password in the Monday email. The sign at the gate is printed once.

In week six a subcontractor finishes and leaves the project. The contractor opens the code in the dashboard, changes the password, and puts the new one in the next email. The old password stops working with the next scan, and nobody has to reprint the sign. The dashboard shows 64 scans that month, most of them before 8 a.m., which tells the contractor the crews check the drawings at the start of the day.

What the password does and does not protect

• It is one shared password per code. It is not a login for each person. Anyone who knows it can pass it on, so change it when the group changes.
• It guards the code, not the destination. If the code forwards to a page on your own website, that page is still open to anyone who has its address. Keep the address unlisted, or protect the page itself as well.
• It does not identify people. The dashboard shows the time, city, and device for each scan. It does not record names.
• It is not the right tool for regulated data. Medical records, payment details, and anything that needs an account per person belong behind your own sign-in page. You can still point a QR code at that sign-in page.

Other ways to limit who can open a code

A password is one of four access controls in QRelix Pro, and they can be combined on the same code.

• Expiration date. The code stops opening at a date and time you choose. This suits an offer or a bid deadline.
• Scan limit. A daily cap, a total cap, or both. This suits an offer for the first 100 people.
• Geofencing. The code opens only for scanners in a city, region, or country you choose. Location comes from the scanner's IP address, so it is accurate to about city level.

When more than one control is on, QRelix checks the geofence first, then the password, then the scan limit, then the expiration date. The security and access controls guide describes each setting. If you want the opposite, a code with no end date, see how to make a free QR code that doesn't expire.

Is this the same as a WiFi password QR code?

No. A WiFi QR code stores your network name and WiFi password so a phone can join without typing. It hands a password out. A password protected QR code does the reverse and asks for one. If the WiFi kind is what you need, the WiFi QR code generator makes one.

What a password protected QR code costs on QRelix

• Free ($0, no credit card). Unlimited dynamic QR codes, every QR code type, editable destinations, custom colors and logo, and scan analytics. Each code works for its first 50 scans and shows a brief QRelix screen before forwarding. After 50 scans the code pauses until you upgrade. Password protection is not part of the free plan.
• Pro ($5.99 per month). Unlimited scans so codes never pause, no QRelix screen, and the security suite: password protection, expiration dates, and geofencing.

You can create and design the code on the free plan and add the password once you are on Pro. Upgrading does not change the QR image, so anything already printed keeps working. The dynamic QR code cost guide compares the two plans, and current details are on the pricing page.

Questions about password protected QR codes

Can I make a password protected QR code for free?

On QRelix, password protection is part of Pro at $5.99 per month. The free plan lets you create, customize, and track dynamic codes, with 50 scans per code and a brief QRelix screen on each scan.

Can I change the password after the code is printed?

Yes. Edit the code in your dashboard and enter a new password. The printed code stays the same and the new password applies right away.

Can a static QR code have a password?

No. A static code holds the destination itself, so the phone goes straight there and nothing can ask for a password on the way. Password protection needs a dynamic code.

Do people need an app to enter the password?

No. The phone camera reads the code and the password prompt opens in the phone's browser.

Can I see who opened the code?

You can see each scan's time, city, and device in the dashboard, and how many scans a control blocked. You cannot see names, because scan data is anonymous.
