[Dixonary] OT please explain
 

Could someone please explain

why modern security ideas (for eg gmail login), etc seem to think that
involving two different machines using two different operation systems
and two different radio pathways is actually safer than one direct access

I feel this fairly critically for most of them demand that I copy a code
received as an SMS message by my smartphone - I live in an area where G4
G5 reception is not reliable and when I am sent a code which is viable
for 10 minutes but may well take a full day to arrive then ...Aargh

It suddenly struck me that to involve 2 operating systems which in my
case are both secureÂ* - (a)Windows 10 pro via internal wifi via phone
landline cable on a fully secured laptop and (b) Android 10 on an
equally secure smart phone but using the phone network - which I presume
is a different radio path via at least a couple of transmission towers -
would seem to me to be increasing the chance of interception.

Am I being stupid? - or what?

PS. I had to remove the phone from my online banking profile because my
bank sent me a required notification by SMS which took 79 hours to
arrive and cost me bank fees because I hadn't taken an action which I
didn't know about (and of course banks are very unforgiving when it
comes to their money)
