The right response depends on whether the leak involved a password, payment card, Social Security number, phone account, medical records or tax information.
1. Verify the breach and identify exactly what was exposed
Read the company’s breach notice carefully, but verify it independently before taking action. Open the company’s official website or app yourself, or call a number from a statement or account you already trust. Do not click links or call numbers in an unexpected email or text; breach publicity often triggers convincing phishing campaigns.

The category determines the next remedy. The Federal Trade Commission directs consumers to IdentityTheft.gov/databreach for a tailored checklist.

Change the password for the affected account first. Then change every account that used the same password or a similar variation. Attackers routinely try leaked credentials on email, shopping, banking and social accounts, so changing only the breached site’s password leaves reused logins exposed.

- Set a new, unique password and change any related PIN.
- Review account-recovery email addresses, phone numbers and active sessions; remove anything you do not recognize.
- Enable multifactor authentication (MFA). The FTC says MFA makes it harder for scammers to log in even when they have a username and password.
A password manager can generate and store unique credentials. For accounts that support it, a USB hardware security key is an optional MFA method; check compatibility before buying one. MFA does not replace password changes, credit controls or reporting.
3. Protect your credit if identity data was exposed
If the notice includes your Social Security number or identity documents, treat the risk as potential new-account fraud. Obtain your credit reports, place a free one-year fraud alert, and consider a credit freeze. A fraud alert asks businesses to verify your identity before opening new credit; a freeze blocks prospective creditors from accessing your file until you lift it. The FTC explains that “a credit freeze makes it harder for someone to open a new account in your name.”

4. Contact banks and card issuers about payment information
For exposed debit-card, credit-card or bank-account data, call the institution’s fraud department using the number on the back of your card, a statement or its official website. Ask whether it should freeze or close the affected account, issue replacement cards or add other controls.

5. Report identity theft and continue monitoring
If you discover an unauthorized account, purchase or other misuse, report it at IdentityTheft.gov. The service can create an FTC Identity Theft Report and a recovery plan. Keep copies of the breach notice, messages, account records and correspondence.
Continue checking credit reports, bank statements, card activity and account-login alerts. Watch for follow-up calls, texts and emails that claim to offer refunds, security checks or credit monitoring. Verify every request through an independently found official channel; never provide a one-time code, password or payment to an unsolicited caller.

How to tell a breach notification is genuine
- Find the company’s website or app by typing the address yourself, not by using the message’s link.
- Compare the notice with an announcement in your existing account or a statement you already receive.
- Call a known number and ask whether the incident and recommended steps are real.
- Be suspicious of urgency, requests for passwords or MFA codes, demands for payment, and unfamiliar download links.
