This will only be an issue for few users, but the guildwars2.com website has no upper limit on the character length of the account password, allowing users with KeePass or other similar management systems to generate valid passwords exceeding 200 characters, which work just fine for anything related to the website account management itself.
However, when using a password of such a length, the actual Client no longer recognizes the password as valid. There seems to be a length limitation in the Client itself as to how many characters it will accept, thus resulting in a truncated (invalid) password submission. Could we either get a statement on the maximum character count allowed for the game Client, or have the limitation lifted entirely?
From personal experience, 60 characters seem to work for both the Client and the website, though I haven’t tested it further than that. Thanks in advance!
