As I said, I don't know all the jargon all that well...I guess I should have clarified text 2fa? I have not had to add another app in order to facilitate accessing any other sites, whether its 2fa or otherwise. I don't know what a passkey is or a hardware key...as I would think would be pretty clear by my self describing as a luddite of sorts...I am aware that EN doesn't 'need' to explain why; however, they have offered to answer questions and/or provide help and do not have enough resources to do so in a timely manner, related to the impending deadline - they themselves have spoken to this. I'm not sure if your tone is intended to be condescending, but it sure comes across that way in your deciding 'that's all I need to know'....that's not for you to decide. No need to answer further, your take on this isn't helpful to me at the moment.
