Data breach check: has your email been leaked?

What the breach check looks at

A data breach is a copy of a company's user database that ended up public or on criminal forums: the email addresses of its users and, depending on the breach, passwords, names, phone numbers, addresses or IP addresses. TraceFind keeps an index of more than 16 billion breach records from several sources and looks your address up in all of them at once.

For each breach that contains the address you see:

• Which service was breached, so you know which account is affected.
• When it happened, which tells you whether a password you still use could be in it.
• What leaked: passwords, phone numbers, postal addresses, dates of birth, IP addresses and similar fields.

The search runs alongside the account check, so you also see the sites the address is registered on. Old accounts you forgot about are the ones most likely to be in a breach and the easiest to close.

How to check your email

1. Create a free account. No email or password needed; you get an account ID and 3 free searches.
2. Run an email search for your address. Results stream in within about a minute.
3. Read the preview. It shows how many breaches and accounts were found. Credits unlock the full records: breach names, dates and the exposed data.

Nobody is notified. The breach lookup reads TraceFind's own index and the account checks use the same sign-up and recovery screens any visitor sees, without sending mail to the address.

What to do if your email was in a breach

1. Change the password of the breached service, and of every other account where you used the same password. Attackers try leaked passwords on other sites (credential stuffing).
2. Turn on two-factor authentication for email, banking and social accounts first.
3. Use a password manager so every site gets its own password.
4. Watch for phishing. Breached names and phone numbers make scam emails and texts more convincing.
5. Close accounts you no longer use. The account list from the same search shows where to start.

The guide How to check if your email was in a data breach goes through each step in more detail.

TraceFind compared with Have I Been Pwned

Have I Been Pwned is the best-known free breach notification service, and a good first stop. TraceFind is built for investigations rather than notifications: one search combines the breach records with the accounts registered to the address, the linked Google account and mailbox checks, and the result can be exported or placed on an investigation canvas.

	Have I Been Pwned	TraceFind
Breach lookup	Yes, free	Yes; counts free, records with credits
Exposed data per breach	Yes	Yes
Accounts registered to the email	No	Yes, 296 sites
Phone and username searches	No	Yes
Export (PDF, CSV, JSON)	No	Yes

For companies

If you are responsible for a team's accounts, checking addresses one by one does not scale. The employee breach monitoring guide explains how companies watch their domains for new leaks and tell staff in time.
