Cavalary: If without a smartphone, an/or without an active plan (so can just receive calls or messages), or without wanting to install a 3rd party tool, you can't even enable the "lesser" form or SMS 2FA, then that makes for less security, not more.
ssling: You don't need smartphone for OTP authentication, there are plenty desktop apps.
Oh, thought it just referred to phone apps.
Either way, I wouldn't install anything not really necessary. Plus, sounds quite similar to needing a client to get your games...
(Heh, recall my AV's support remarking at one point how lean and clean my installed programs list was, especially if ignoring the games, when I had to send that sort of system report, and it probably became even leaner since, looking first for portable software even if I do need something, or if I need to replace something I already have installed.)
But we're going way off topic here, and this is not how this thread should end, and it does seem that it's nearing that time, so before it'll be locked I just want to take the opportunity to thank finkleroy one more time for all the time and effort put into it, and zeogold and moonshineshadow and IAmSinistar before, and of course all the donors who made it all possible.
Just as a reminder of the threads and hosts:
