DAE hate two-step verification systems?

I already have the passwords of both my Steam account and the password for my Steam account's gmail to keep others from accessing it, so why do you need me to get another device, log into my gmail, find the code, and type that code into my Steam account just to make absolutely sure that some genius computer geek can't guess the password of my Steam account? It's not like it's a database of classified Pentagon documents that you need to be hyper-protective about, and all this system does is create a pain in my ass for whenever I want to play some video games and this stupid two-step irritation system pops up out of nowhere to "safeguard" every step of my login like it's some kind of digital nanny. Not once have I ever thought to myself "thank goodness for this system having to force would-be hackers to type in this code that they would guess otherwise if they could guess my password!"

Obviously protecting your virtual possessions are important, but does anyone else feel like two-step verification systems are overkill?
