Hmm, authenticators definitely help, but there are other simple measures you can take to increase account security on your end.
First of all, use the remember password option in the GW2 launcher. The reason it's a good idea is it prevents you from entering your password each time you login, and it is a hard counter against keyloggers that may get installed somehow.
Next, make sure your GW2 password is secure. In other words, make sure it's a combination of Upper and lower case letters, number, and symbols (i.e. !@#$%^&* and all that jazz as GW2 allows them). If by some chance, someone figures out your email address, they won't be able to brute force your account password.
Third, use a good browser, i.e. (Chrome and firefox) and install the adblock "extension/addon.
Lastly, I recommend using last pass. It's an excellent password manager, and also serves as counter to keyloggers since it autofills passwords. It's quite easy to use and here are a bunch of tutorial videos out there explaining how to use it and such. I do recommend that you check the remember password option so it will automatically log you in. Also, add a google authenticator to your account if you have a smartphone, and add said computer to the trusted computers. This way, it won't bug you for a google authenticator code on your trusted pc. However, if by some chance someone gets your lastpass master password they won't be able to access your account because it'll ask for the google authenticator code.
Oh, and don't forget the usual antivirus software and what not. I honestly just use Microsoft security essentials.
