Learn about data breaches, how to check if you're affected, and what steps to take to protect yourself.
What Is a Data Breach?
A data breach occurs when unauthorized individuals gain access to confidential data — typically stored by companies and organizations. This can include:
- Email addresses and passwords — the most commonly leaked data
- Personal information — names, phone numbers, addresses
- Financial data — credit card numbers, bank accounts
- Identity documents — SSN, passport numbers, driver's licenses

What to Do If You've Been Breached
Change Your Passwords Immediately
Start with the breached account, then any account where you used the same password.
Enable Two-Factor Authentication (2FA)
Add an extra layer of security. Use an authenticator app over SMS when possible.
Check Financial Accounts
Monitor bank statements and credit reports for unauthorized transactions.
Set Up Breach Alerts
Register on Have I Been Pwned to get notified of future breaches involving your email.
Consider a Credit Freeze
If sensitive financial data was leaked, freeze your credit with the major bureaus to prevent identity theft.
Use a Password Manager
Generate unique passwords for every account. Popular options: Bitwarden (free), 1Password, Dashlane.
