Hello. In HA I have generated QR code with random number. It contained URL URL-Based Tag - Home Assistant<tag_code>. By reading that QR code with generic QR reader, it got detected it in my own HA server. That means that no authorization was necessary?
I would like to use QR code for authorization - that HA server generates code, displays it on screen and then user reads it with his mobile device and only if the user is authenticated into HA companion application or browser, then the automation on server starts.
Is that achievable?
