I cannot even put into words how much the Reset Password System for Guild Wars II aggravates me. If you used a password in the past, no matter how long ago it was, you can’t use it again.
So I literally have to sit here for 10 minutes trying to come up with a new password and it’s extremely tedious every time I forget.
Is it possible to simplify it and just make it so that we can use old passwords as well?
They don’t want you to use old passwords because many of them were compromised by people using them in unsafe sites. Since they don’t exactly which ones are unsafe they banned them all.
What AP said is true. But I’m not discounting the frustration, as I’m facing it with an email provider that keeps disabling my current password, requiring me to dream up 2,1064 different passwords, none of which I can remember.
The whole process is built with solid intentions, and it is effective — note this article: https://www.guildwars2.com/en/news/mike-obrien-on-account-security/ -- but there can be a bit of frustration involved, it’s true.
