There is a site https://webauthn.io/ when you click the registration button, a window is displayed:
Although I expect this window, which gives the option to choose auto-authentication via qr or other methods:
I want to understand why they let me choose to log in via QR, but they immediately let me enter the pin and the browser window does not even appear, despite the fact that on the same site on another computer everything works as I want
I tried to log in on other sites in other browsers, the result of one entry by qr is not displayed
