SB007 Checks whether passwords (or other personal data) have appeared in known data breaches

Tools such as haveibeenpwnd.com can be used to check if passwords (or other personal data) have been leaked in known data breaches.


Why is it important?

Staying up-to-date with data breaches is important.

Knowledge of an account's details being leaked can provide valuable time to secure an account. Login details can be changed and any recent activity reviewed.
