No, the reason they're going to hit a dead end is because you tried to ressurect discussions that finished literally years ago - discussions started by now inactive accounts, replied to by people whose answer won't have changed. You posted 4 TIMES asking people whose discussions had established there was no 2fa hardware support if there was 2fa hardware support - they had already said no, and you came in between 1 and 6 years later to ask again.

Instead of starting a new, visible discussion on the steam community, where topics are boosted by recent interactions, and it will be seen by the most relevent people, not just the randomers coming through google looking for the same answer as your, but for some reason you chose to ask people who have forgotten they ever needed help with this issue if they ever found an answer.

Lastly, I want to point out how fucking stupid and infantile it is that you're not only asking the question again, but asking in multiple year old discussions: Steam has repeatedly said that Steamguard is their 2fa, and that's it. Your "bu- bu- bu- i'm important i need hardware to stop evil hackers from targetting my vibeo gane" is absolutely irrelevent to them, a position they have not been secretive about.
