To log in, a unique hash value in the QR code should match the QR code on the blockchain network. Hence, there stays utmost security.

Why the Use of QR Codes?

Due to the size and structure of QR codes, the two-dimensional black and white barcodes you call QR codes are quite versatile. And since most people carry a smartphone everywhere, they can swiftly scan QR codes with their cameras. Moreover, as QR codes are relatively convenient to program and accessible for most smartphone users, they can be an effective and powerful tool.
QR codes also have many usages. For example, QR codes can link to a webpage, start an app or even file download, share contact information, start a payment, and more. Covid19 pandemic forced businesses to be innovative with touchless experiences, and QR codes offer an easy way to transform a physical touchpoint into a digital interaction. During the time of Covid, QR codes turn out to be a famous way to communicate Covid policies, look at the café menus, check-in for an appointment, and much more.
However, a user should have previously registered an authenticator app against their account to use the QR Code for the Login authentication method. During overall registration, a procedure permits the authenticator app to authenticate the user and validate QR Code login transactions on their behalf. The authenticator app gets a Refresh Token that gives it long-lived authority to perform such a task. When an application initiates a QR Code login, the blockchain Security Verify generates a new QR Code transaction. For example, the hash matches with the hash on the blockchain network to ensure authenticity.

QR codes &the Authentication Loop

Well, most devices can get used to logging in to another device. Blockchain-based secure QR codes offer paths for users to validate on any device, from any device. Once a user has logged in some place, they should be in a position to log in anywhere conveniently. You can make the login process an absolutely excellent user experience using blockchain-based QR codes. It would not just be smooth, efficient and effective but also tamperproof.

Moreover, blockchain-secure QR code provide direct access to your web account. You can protect them as you would with any username and even password combination. The unique hash value in the blockchain QR code is immutable by nature. Hence, there is no scope for fraud or any attack.
It is also true that scanning a fake QR code can put your privacy and online security in danger. However, there are measures you can take to dodge or stop potential security threats.

Like you can start using blockchain-based secure QR codes. Whether a secure file sharing blockchain or logging in, encryption makes everything immutable and tamperproof.

The Bottom Line

The largest tech companies are already hugely embracing QR codes. Whether for logging in or transmitting data or more, QR codes are great.
