Click to check email breaches on popular hack lists
One of my older emails was tied to DDO and was flagged with the following warning:
Dungeons & Dragons Online: In April 2013, the interactive video game Dungeons & Dragons Online suffered a data breach that exposed almost 1.6M players' accounts. The data was being actively traded on underground forums and included email addresses, birth dates and password hashes.
DDO has since changed forum and game account access. My email that was flagged is no longer used and what it used before does not have the same password for other things.
There are numerous reasons to change passwords regularly regardless of the hassle. I don't wish what I've gone through on anyone. You can try a password manager. Do a google for that, there are many. I do strongly suggest NOT using anything Kaspersky as they are under investigation for contributing to foreign government hacking.
Good Hunting !
