Has your data been leaked?

Search an email, phone number or username to see which data breaches it appears in, then get a simple plan to protect yourself.

This is a search, not a sign-up. We never create an account or store what you enter.

Your exposure report

New search
Searching breaches and public sources. This can take up to 20 seconds.

How it works

  1. 1

    Search

    Enter an email, phone number or username you use online.

  2. 2

    See the risk

    Find out where it leaked and how that data could be misused.

  3. 3

    Fix it

    Follow a short checklist with direct links to secure each account.

Verify it's your email

We'll send a 6-digit code to your inbox. Only the owner of the email can see the full results.

Turn on breach alerts?

We will email when:

  • A site you use reports a breach or attack
  • Your email shows up in a new leak (we check weekly)

What we keep

Your email, the sites you have accounts on, and the leaks you are already in, so we only tell you about new ones. It is stored encrypted, used only for alerts, and never sold or shared.

How to stop

Every alert has a stop link, or turn alerts off here any time. Stopping deletes everything we kept.

Read our Privacy policy and Terms.

Check a password

Hackers try passwords from old breaches first. Find out if yours is one of them.
