Frequently Asked Questions
Is my email address stored when I check?
No. Your email is only used to query the Have I Been Pwned database. We don't store, log, or track any email addresses checked through this tool.
My email was found in a breach. What now?
First, change your password on the affected site immediately. If you used the same password elsewhere, change it on those sites too. Enable two-factor authentication wherever possible.
How can I prevent being in future breaches?
Use unique, strong passwords for each account. A password manager makes this easy. Enable two-factor authentication on important accounts. Be cautious about which services you share your email with.
