My point in the original article was: depending on the circumstances, two-factor authentication is like a fence —
hackers anyone can jump it.
Two-factor authentication literally gives the impression of a pharmaceudical drug. It is promoted as a guidance, when in reality — the person, that the technology gets promoted to, gets fooled to believe that this is the only secure method — and to completely ignore the fact that...
Data breaches happen!
Although it's benefitial to install 2FA on Linux, who is to say there aren't/won't be vulnerabilities that will allow the hacker to "jump the fence" in the long run?
Time and time again, we've seen the way Discord handles authentication & how anyone can jump through accounts with the matter of a single token (2FA also being bypassed as well!) — given the social engineering.
In short, putting two-factor authentication is a huge boost to secure your accounts, but isn't a guarantee.
