Guild Wars 2

Yes, you are correct. Here’s the difference in names:

Account name = log-in game = user name = An email address at account creation and used to log in to the account. Your account name can be changed through a support ticket.
Display name = A rather generic (in most cases) alias that identifies you in the game and on the forums but protects your e-mail address/user/account/log-in name. After all, Fred@ThisEmailProvider.com is part of your account credentials. No one can or should be able to hack or assume your identity using LittleFreddyFooFoo.1234.

Andy section eight.1062:

I sent in another ticket. I hope resetting my display name an pass will fix it this time. I need my GW fix! I am not giving up on this until it gets fixed.

Again, you log in with your Account Name which is an e-mail address and not your Display Name. We don’t reset Display Names, and changes to Account Names would not, I don’t think, correct this issue.
