You know what QR Codes are and what they do. They’re advanced level barcodes that can store up to 7,089 characters.

You would’ve seen them being used for marketing, payments, and even inventory management. And you’re now considering using them for one of your use cases.

And you’re right. QR Codes make print media readily actionable. As a result, end-users simply need to pull put their smartphones to scan the QR Code and see the encoded content. As easy as clicking a picture, right?

But here’s the thing—anyone with a smartphone can scan a QR Code to access the data encoded in it. While it helps end-users easily decode the QR Code easily, it is also a matter of concern if you want to restrict the access to the encoded data.

And that’s probably your concern too. You want to use a QR Code but restrict access to it at the same time. And you’re wondering—is it actually possible to do that?

And the answer is—yes. You can restrict the data in your QR Code to allow only authorized personnel to access it. How? By adding a password to it. We call them—password-protected QR Codes.

A. What are password protected QR Codes

Password protected QR Codes allow you to share your private data with only authorized people. When end-users scan it, they are prompted to enter the required password to be able to access the data. That simple!

password protected QR Codes: scanning the QR Code

Here is how a password protected QR Code works:

1. You head on to a QR Code generator that allows you to password protect your QR Code
2. You create the QR Code and add password protection to it
3. Next, you add the QR Code on required documents or print media creatives
4. You share the password with people you want to access the data
5. They scan the QR Code and get a prompt to enter a password
6. They enter the password and see the encoded content

Note that you can only make dynamic QR Codes password protected. Not sure what it means?

Depending on how the data is stored, QR Codes can be divided into two categories—static and dynamic.

The data is encoded directly into static QR Codes. Hence, they are permanent in nature. That means once created, they cannot be edited. To do that, you will have to create a new QR Code altogether. In addition, you can also not track the scanning activity of static QR Codes.

On the other hand, the target data is not encoded directly into a dynamic QR Code. It stores a short URL (usually provided by QR Code service provider) that redirects to the actual data.

Hence, a dynamic QR Code can be edited anytime you want. Yet it will remain the same. No need to reprint it. In fact, it even helps you monitor its scanning activity. For example—how many people have scanned it, when and where did they scan it, etc.

B. What can you share with password protected QR Codes

There’s a lot you can share with QR Codes. From sharing a website link, text, and venue location to a customized landing page, a secure QR Code allows you to share almost any sort of content. For example:

1. Confidential Documents

Say you want to share confidential documents with your colleagues, investors, customers, or any other stakeholders. Here a password-protected QR Code can help you out. 

When end-users scan the QR Code, they’ll be prompted to enter the required password. Once they do it, they’ll be able to see the encoded documents.

For such use cases, you can create a PDF QR Code, a Text QR Code, or even a Website URL QR Code. And add password protection to it.

2. Download Links of Paid Content

Suppose you offer downloadable content such as music and games. You want to share it only with the people who pay for your content. Here a password protected QR Code will let only your customers access your services.

To do it, you can create an Audio QR Code, a Text QR Code, or a Website URL QR Code.

3. Special Message

Say it’s your partner’s birthday and you want to send them a special message on a birthday card. You want only your partner to see the message and nobody else. Simply adding a QR Code with a password to the birthday card will help you do this.

Here, you can create an Image QR Code (if the target content os an image). A Website URL QR Code (to show a video or an image gallery). An audio QR Code and much more.

You can actually create more than 25 different types of QR Codes. For example—a Website URL QR Code, QR Code for app link, a Business Card QR Code, a coupon QR Code, and an App Store QR Code. You can go through the list to decide the best one for your use case.

4. Regulate the contest participants

Say you are planning to organize a contest. And you want to share specific content with each participant to ensure fair gameplay.

Here, you can just password- protect the content to be shared with QR Codes. You can then share the required password with specific people.

For example, you can conduct a treasure hunt game using QR codes. These QR codes will show various information such as hints and locations to clues. And you can use a password-protected QR code to restrict nonparticipants from accessing the hints.

5. To protect that data on inventory tags

You probably know how often QR Codes are being used in inventory management. That’s because they are damage-resistant and can hold more information than traditional barcodes. 

And for smooth inventory handling, you need to out QR Code-based inventory tags where they can be readily scanned and verified. But this also exposes them to breach since anyone can scan them.

So, ensure that you password-protect the QR Codes if you don’t want unwanted access to them.

6. Pre-release of marketing materials

Having some campaigns being pushed ahead of time is common in print media marketing. But that content is not intended to be accessible for everyone. 

And needless to say, to stop unauthorized people from accessing the information, a password-protected QR Code is all you need.

7. Beta access to mobile games

If you are into the gaming industry, you’re already aware of the utility of QR Codes. They can be used to connect in-game players to your website, upcoming releases, leader boards. etc. QR codes on gaming merchandise or ads can drive users to special landing pages focused on mobile games user acquisition. Creative use of QR codes provides a seamless way for players to learn more about your games and potentially become loyal users.

C. How to create a password-protected QR Code

The first thing you need to create a QR Code is—a QR Code generator. Ad here you will need a best QR Code generator that offers password protection. How do you find one?

If you do a quick Google search, you will probably get a list of such search results. And to decide the best one for your use case, you will have to compare all of them one-by-one.

But this will take a lot of time and effort. Don’t worry, you don’t really have to do that. We have compiled a detailed comparison chart of the topmost QR Code generators. You can go through it to decide the best one for your use case.

Once you finalize a QR Code generator, the next step is to create your password protected QR Code.

E. Best practices for password protected QR Codes

Password-protected QR Codes can add an extra layer of security to your QR Code content, ensuring that only those with the correct password can access the information. Here are some best practices for creating and using password-protected QR Codes:

1. Use a secure QR Code generator

Choose a reputable and secure QR Code generator that offers password protection as a feature. Avoid using random online generators that may not prioritize security.

2. Strong passwords

Use strong and unique passwords for each QR Code. A strong password typically includes a combination of uppercase and lowercase letters, numbers, and special characters. Avoid easily guessable passwords, such as “123456” or “password.”

3. Inform recipients about password

If you’re sharing password-protected QR Codes with others, ensure they know the password. Communicate it securely through a separate channel, such as a secure messaging app or in person.

4. Consider encrypted content

If the content behind the QR Code is sensitive, consider encrypting it before generating the QR Code. This way, even if someone scans the QR Code without the password, they won’t be able to access the information.

5. Expiration dates

If the information behind the QR Code is time-sensitive, set an expiration date for the QR Code. This ensures that even if someone gains access later, the information will no longer be relevant.

6. Test QR Code functionality

Before distributing the QR Code, test it to ensure that the password protection is working correctly. Make sure that scanning the Code without the password doesn’t reveal sensitive information.

7. Regularly monitor access

If the information behind the QR Code is particularly sensitive, consider monitoring access. Some QR Code generators provide analytics that can help you track when and how often the Code is scanned.

8. Use a trusted QR Code scanner

Encourage users to use a trusted and up-to-date QR Code scanner app. Some apps may have built-in security features to handle password-protected QR Codes more securely.

9. Rotate passwords periodically

For added security, consider rotating passwords periodically, especially for QR Codes that need to be accessed over an extended period.

10. Be mindful of lost passwords

If you’re distributing password-protected QR Codes to others, consider how you’ll handle situations where someone forgets the password. Have a plan in place to help them recover or access the information if necessary.

11. Educate users

Provide clear instructions to users on how to use password-protected QR Codes. Ensure they understand the importance of keeping the password secure and not sharing it with unauthorized individuals.

12. Backup QR Code content

Ensure you have a backup of the QR Code content and the password in case of emergencies or loss of access.

You now know everything about password-protected QR Codes. This includes—what are they, how do they work, how to create them, and how to edit them.

A password-protected QR Code, just like any other QR Code, provides easy access to the encoded data. And it even helps you limit access to it in a few simple steps.
