This made me laugh out loud. I'm working in a multi-tenant, multi-subscription environment with Azure AD just now. MS force you to use 2FA and I picked the wrong 2FA app.
Now it's completely and utterly comical trying to work out which generated 2FA auth code I need to key in when auth'ing in Visual Studio because there are absolutely no visual cues as to which subscription it's trying to authenticate to. You can't tell VS that "I'm only interested in auth'ing to this particular subscription". Now it prompts me for almost every subscription we use and it's a whack-a-mole experience. They really need to fix the UI/UX in VS for this.
Of course when it comes to mandatory password change time I have to go through this pain all over again.
