Question 1

What does the Email Leak Checker look for?

Accepted Answer

The Email Leak Checker queries multiple data breach databases to determine if your email address or domain has appeared in known data breaches. If found, it shows which breaches included your data and what type of information was exposed (passwords, phone numbers, IP addresses, etc.). This helps you identify accounts to secure with a password change and multi-factor authentication.

Question 2

My email appeared in a breach — what should I do?

Accepted Answer

If your email address was exposed in a breach: (1) Immediately change the password for that specific service. (2) Change the password anywhere you reused the same credentials. (3) Enable two-factor authentication (2FA) on all important accounts. (4) Check if your password appeared in breach dumps using haveibeenpwned.com. (5) Monitor for phishing emails that may use the exposed data to appear legitimate.
