I mean, generating a one time QR code for login is one thing. It’s the equivalent of a one time password. But a permanent QR code is not that. They still aren’t inherently secure, but they can be used in situations where showing a code in plain text would be just as secure.
Yeah, my language was overly broad. You can use QR codes as part of a system where the security is going on elsewhere, but the integrity of the QR code itself isn’t something that can be relied on for security.
