Search for username/password matches in Mark Burnett's publication of 10 Million accounts
Am I just doing this to collect usernames and passwords that are searched?
No. I'm not logging the post data of requests that come to my server through this method.
You can't trust anyone on the internet, but also, not everyone is out to get you. Even so,
I recommend you only search the first 4 characters of a password as a good practice or
simply search common usernames you have used.
Why put this data here?
Many people expressed an interest to see if their username/password appeared in this dump of 10 million.
Does it matter if your information is or isn't in the database? Not really.
If it is, it definitely warrants a change to your password information, but this data dump is a tiny sample of the hundreds of millions of accounts that have been publicly dumped over the years. Mark's FAQ covers many good practices on more through searches of the interwebs for your account credentials.
