Guild Wars 2

Is it possible to have different password for gw2 forums and for playin’ the game ?

i dont belive so since it is the same account you use, if you are concerned about security, add a add mobile aythetification on your account and it will be next to impossible to access your account unless someone actually steal your phone too, since it generates a random 6digit number every 60 seconds or so i think taht you avhe to type in after you typed your username and password
