How to Generate a Temporary QR Code and Why Should You Use It?

Users of messaging apps share content, contacts, and profiles on some of the most used platforms in the world such as Telegram, Instagram, WhatsApp, and more. However, security is the priority as users don’t want the leakage of any personal information that could threaten their safety online.

Telegram avoids the misuse of information among users and prevents them from chatting with each other without having their phone numbers added.

To improve security, the app announced several tools including one that has the ability to generate temporary QR codes. The new functionality is part of the app’s most recent global update, which also helps optimize the user experience.

How to share a temporary QR code?

Telegram users can now utilize temporary QR codes with the app to share their contact details or profile on the platform without leaving any trace. This way, it is now possible to spread such information through a QR code that will expire at any given time.

When the code expires, the embedded content will stop being accessible to anybody scanning it.

You can find this option by touching the three horizontal lines in the upper left, and then clicking on your profile photo. A menu will pop up, and you will see the QR code icon again. You just have to touch it and you will see your own customizable element, so you can share it with whoever you prefer.

For your QR code to be temporary, two conditions must be met: that you do not have a username in your Telegram profile and that you have the phone number hidden from everyone. This way, they can still add you without sharing your phone number, but only for a limited time.

In this regard, according to the Telegram blog, you can generate a temporary QR code if you do not have a username and you hide your phone number from everyone. By scanning the code, people will be able to instantly add you as a contact, without needing to know your phone number.


Telegram has become one of the best options besides WhatsApp and other messaging apps. The great usability, the safety features, and the constant innovations such as the temporary QR codes make Telegram a strong, growing contender.
