What to do if your data was leaked

Finding your data in a breach is unsettling, but the response is straightforward. Work through these steps in order.

Step 1: Scan your email

Enter your email address on the LeakedSource homepage to see which breaches you appear in and what types of data were exposed.

Step 2: Review the details

Sign in (a free account works) to see the full breakdown of each breach, including the specific data fields that were compromised — passwords, phone numbers, addresses, and more.

Step 3: Change compromised passwords

For every breach that exposed a password, change it immediately on the affected service. If you reused that password on other sites, change it everywhere. Use a unique, strong password for each account — a password manager makes this painless.

Step 4: Enable two-factor authentication

Turn on 2FA on all accounts that support it, starting with your email, financial, and social media accounts. Use an authenticator app rather than SMS when possible.

Step 5: Check for identity theft

If sensitive data like Social Security numbers, government IDs, or financial details were exposed, monitor your credit reports and consider placing a credit freeze with the major credit bureaus.

Step 6: Enable continuous monitoring

Set up breach monitoring in your LeakedSource account so you're alerted instantly when your data appears in any newly discovered breach. Breaches often surface months or years after the actual compromise — monitoring means you'll never find out late.
