Twitter 發了公告請大家改密碼：「Keeping your account secure」。不只是 Twitter 自家的密碼，如果你有重複使用同一組密碼，也建議一起修改：
Out of an abundance of caution, we ask that you consider changing your password on all services where you’ve used this password.
雖然使用 bcrypt，但因為透過 log 記錄下了未加密的密碼，所以就中槍了：
We mask passwords through a process called hashing using a function known as bcrypt, which replaces the actual password with a random set of numbers and letters that are stored in Twitter’s system. This allows our systems to validate your account credentials without revealing your password. This is an industry standard.
Due to a bug, passwords were written to an internal log before completing the hashing process. We found this error ourselves, removed the passwords, and are implementing plans to prevent this bug from happening again.
這時候就要再推 Password manager 這種東西了，在每個站台都使用完全不同的密碼，可以降低這類問題帶來的衝擊...
