Re: Wanting to use 2FA is one thing...
"Why should it need connectivity, ... "
Sure, but for those of us in areas where there is no cell connectivity (most of rural Canada), we often don't have, let alone carry, a cell phone.
Also, pardon my ignorance, but how would I connect a cell phone to my computers? Do I need to install some kind of USB wireless device? I am indeed interested in 2FA, but it seems that there are different explanations of how to do it, each with a different set of unexpressed assumptions.
