I got the email from Adobe Customer Care informing me that my password was part of a great password leak reported by XKCD. So I’m supposed to change my password anywhere that I used that password. Unfortunately, Adobe has unhelpfully reset everyone’s passwords, so I can’t test what my password was or see the hint, to know which password I need to reset. Is there a victims’ help database that allows me to look up my old password hint so that I can figure out which password I used at Adobe?
There are many services online that will the query the leaked database and tell you your hint an hints by other people using the same password, one of them is provided by Lastpass at https://lastpass.com/adobe/.
