After a data breach
A company you use got hacked, or you got a breach letter. Here is what to do, in order. Most of it is free.
Careful: scammers send fake "breach" emails too. Get breach details from the company's real website, not a link in a message.
- See what leaked. Check your email address at Have I Been Pwned. It is a free site that shows which known breaches included your email.
- Change that password, and any other account where you used the same one. A password manager makes this easy.
- Turn on two-step login (MFA), starting with email and bank. CISA explains how: Turn on MFA. See app vs text codes.
- If your Social Security number leaked, freeze your credit at all three bureaus. It is free.
- Check your credit reports at AnnualCreditReport.com.
- Follow the official checklist. IdentityTheft.gov/databreach has steps by type of data leaked.
- Watch for follow-up scams. After breaches, scammers often send emails that use the leaked info. Use our scam email checklist.
If someone already used your info
Report it and get a recovery plan at IdentityTheft.gov.
