If your account was compromised your Adobe account was already locked a month ago. If, however, you are unsure if your email address was in Adobe's records (and it is quite likely that many of the 150 million users affected are), you can check online if your email address is included in the leaked data. This service is provided by a third party, and AfterDawn is in no way responsible for it's behaviour. While we believe the service is legit, there are no guarantees of it.
Should your email address be affected and you have used the same password in Adobe's services as well as other web sites, it is advisable to change your passwords immediately.
We recommend using a password manager to easily keep your passwords in check and avoid using the same password over and over again. Both KeePass and LastPass are very good choices.
