I had my security token since when I bought the CE nearly two years ago.

I never used it because I thought it would just be a hassle and take longer for me to log in, but after having the same problem as yourself (I was traveling a lot) I decided to give it some use and haven't turned back yet.

So yes, use your Square Enix Co Ltd. Official FINAL FANTASY XIV Security Token (TM) today, you won't regret it.
