Post-Update OOBE on Windows 11 (on 22621.2134 / 22H2; this laptop was in storage for a while) with an MSA generated a flood of Authenticator 2FA requests _without_ showing anything other than "Just a moment..." on screen, especially not showing the 5-digit 2FA request ID.

WTF? Isn't that how some recent 2FA hacks worked? You flood the victim with random 2FA prompts until they accidentally hit "accept"?

MSA now in "You need to verify your identity." state, so seemed legit.
