While I appreciate and completely agree with everything in Mike O’Brien’s post this date (https://www.guildwars2.com/en/news/mike-obrien-on-account-security/), some people saw this one coming and planned ahead. My husband and I have been gaming and dealing with hackers and bots for years. We report them as soon as we find them in the game and have gotten VERY good at ferreting them out. We have worked hard to ensure that not only does every email account have it’s own unique password, so does our network, each game we play, etc. Given our natural enthusiasm and excitement for the game as we followed its development over the years, we definitely wanted it to be secure for us from the start.
This being said, I already have a completely unique password to GW2. It’s not something anyone is likely to guess. We check for keyloggers and other invasive software routinely and are careful where we download anything from. I have not had any issues with my account and am extremely confident it is secure. I am so confident, that I really do not want to change my password at all and hope it doesn’t become mandatory for everyone, even those that thought ahead ~ the minority though we may be.
Just my two cents worth.
And yet, I know it’s for a good reason, so I do it and some up with something very different. In your case, if you’re confident that your password is very secure, try one of the suggestions above and if it doesn’t fail (because it’s on the “known password list”) then consider that an extra level of security.
