Frequently Asked Questions About Data Breaches
What is a data breach?
A data breach happens when hackers steal user data from a company’s systems — including email addresses, passwords, phone numbers and payment details. This stolen data is often sold online or published publicly.
What should I do if my email was in a breach?
Change your password for that service straight away. Make sure you use a unique password for every account — a password generator can help. Enable two-factor authentication (2FA) for extra protection.
Is this check safe?
Yes. Your email is only used to query a public breach database. It is never stored, logged or shared anywhere.
