I have known a fair few people over the years who have had security tokens --to be able to login at work.-- For work purposes, i.e. you need it to do your job so it may be required at any point. TFA is saying people will leave it just by the PC they use most often, i.e. at home, which defeats the point. I think the use of smart phones for 2-factor is the way to go, since it is not something else I need to carry around. Up until recently Barclays Bank (in the UK) had a fairly bulky card reader which I would insert my card, tap in my pin and it would generate a secondary password (I also have to chose letter X and Y from my password). They now have a smart phone app. Much simpler for me now.
