It feels like every few weeks or months I get an email about one of my accounts possibly being compromised by hackers. Instead of waiting for the company to send out an email about the data breach there is a way to automatically have your account tracked by haveibeenpwned.com. The website might not sound like the most legitmate place but it is. Users can search their login names or setup an automatic alert so they can be notified when the account is found in a data breach report.
Adding every account or login might be a bit tedious so focusing on accounts that have personal or financial information would be the best place to start. If you are a developer there is even an API that can be used to search the database.
