How Passwords Get Leaked
Data breaches expose millions of passwords each year. Major breaches (LinkedIn, Adobe, Yahoo, Equifax) have leaked over 3 billion credentials. Attackers use these leaked passwords to break into other accounts — because most people reuse passwords.
How to Check for Leaks
- Visit HaveIBeenPwned.com and enter your email
- Use our Password Strength Checker to test if your password appears in common breach databases
- Check Google Chrome's built-in password checkup in Settings → Passwords
- Enable Firefox Monitor for automatic breach alerts
What to Do If Your Password Was Leaked
- Change the password immediately — on ALL sites where you used it
- Enable two-factor authentication (2FA) on every important account
- Use a password manager to generate unique passwords
- Monitor your accounts for suspicious activity
- Consider credit monitoring if financial data was exposed
Frequently Asked Questions
Should I be worried if my password was in a breach?
Yes. Change it immediately and check all accounts that used the same password. Enable 2FA everywhere possible.
Is it safe to check my password on breach-checking websites?
Reputable services like HaveIBeenPwned use k-anonymity — they only send a partial hash of your password, never the full thing.
